Lyubomir T. Gruyitch
The human has been developing automatic control in order to satisfy three natural imperatives (three instincts): the instinct of selfpreservation, the species preservation  the sexual instinct, and, in my opinion, the game instinct (the game in its widest sense that incorporates art) with the best quality, minimal efforts and spending less time. I have devoted my teaching and research continuously to dynamical systems and systems control; last two decades also to TIME properties, relativity.

The book presents the proofs that Einstein`s claims (lifted to the level of uncontested postulates) on the relativity of time itself, on the existence of several times and the time speeds, on the time dependence on space (frames), on the invariance of the light speed are wrong and physically meaningless. The book discovers Einstein`s tacit assumptions accepted a priory, which form the basis for all his mathematical results. The book explains and shows that all the assumptions are inacceptable, which makes all his mathematical results formally valid only under such assumptions and that his theory represents from the formal mathematical view point exclusively a singular case.

Time and Consistent
Relativity: Physical and Mathematical
Fundamentals establishes a new and original theory of time
relativity, which is fully consistent. It explains why Einstein`s
theory of time relativity is physically meaningless and
mathematically based on tacit inacceptable assumptions, and why it
represents the singular case from the mathematical point of view.
The consistent relativity theory established in the book represents
an exit from the situation created by Einstein`s theory of time
relativity.
This original book presents novel results on time and its
relativity that constitute the consistent relativity theory. The
results are free of mistakes, inconsistencies, and paradoxes of
Einstein`s time relativity theory. The author’s original
discoveries and results constitute the new physical and
mathematical fundamentals on time and its relativity. The book
presentation is concise, clear, and selfcontained. It covers the
phenomenon of time and its properties and results in a definition
and characterization of time. It enables the great variety of new
mathematical results presented in the form of theorems and their
corollaries and specifies the necessary and sufficient conditions
for the corresponding statements to hold. The proofs are
rigorous.
This book:
 explains the physical nature of time
 presents the definition and characterization of time
 explains the physical sense of time relativity
 rejects Einstein’s time relativity theory as the general one
 proves that Einstein’s time relativity theory represents a singular case valid under tacit, physically meaningless and mathematically inacceptable, assumptions
 generalizes and extends the GalileanNewtonian meaning of time and its relativity
 introduces various new classes of mathematical transformations related to temporal, spatial, and velocity coordinates and proves the necessary and sufficient conditions for their validity
 discovers a great specter of new results on the time uniqueness, relativity, temporal speed
 discovers and proves a great specter of new results on the velocity and its transformations
 discovers and proves a great specter of new results on the light speed and its invariance and noninvariance

Features
 Introduces the full transfer function matrix, which is a crucial complex domain characteristic of linear dynamical and control systems that can be used under arbitrary inputs and initial conditions
 Establishes the new fundamentals of the complex domain theory of linear dynamic and control systems
 Shows how the full transfer function matrix enables you to synthesize control of linear systems to work more effectively in real environments
 Discusses tracking and trackability fundamentals and their significance for control synthesis
 Presents novel, sophisticated approaches and methods for tracking control design
 Includes theorem proofs in the appendices
Summary
The primary purpose of control is to force desired behavior in an unpredictable environment, under the actions of unknown, possibly unmeasurable disturbances and unpredictable, and therefore probably nonzero, initial conditions. This means that tracking and tracking control synthesis are fundamental control issues. Surprisingly, however, tracking theory has not been well developed, and stability theory has dominated. Tracking Control of Linear Systems presents the fundamentals of tracking theory for control systems. The book introduces the full transfer function matrix F(s), which substantially changes the theory of linear dynamical and control systems and enables a novel synthesis of tracking control that works more effectively in real environments.
An Introduction to the New Fundamentals of the Theory of Linear Control Systems
The book begins by reexamining classic linear control systems theory. It then defines and determines the system full (complete) transfer function matrix F(s) for two classes of systems: inputoutput (IO) control systems and inputstateoutput (ISO) control systems. The book also discusses the fundamentals of tracking and trackability. It presents new Lyapunov tracking control algorithms and natural tracking control (NTC) algorithms, which ensure the quality of the tracking under arbitrary disturbances and initial conditions. This natural tracking control is robust, adaptable, and simple to implement.
Advances in Linear Control Systems Theory: Tracking and Trackability
This book familiarizes readers with novel, sophisticated approaches and methods for tracking control design in real conditions. Contributing to the advancement of linear control systems theory, this work opens new directions for research in timeinvariant continuoustime linear control systems. It builds on previous works in the field, extending treatment of the system transfer functions, stability issues, the plant–control relationship, and control synthesis.

ABSTRACT
The discovery of the full transfer function matrix F(s) of the linear dynamic system eliminates the deep and essential lacuna of their existing theory. It describes in the complex domain how the system simultaneously transmits and transfers both the action of the input vector and the influence of all initial conditions on the system output behavior. It has exactly the same properties as the classical system transfer function matrix G(s) that is valid only under all zero initial conditions. The full transfer function matrix is determined (together with all its submatrices) for the three classes of the systems, one of which is newly discovered.
The full transfer function matrix F(s) is the basis for the new, full (complete), block diagram system technique. It is established in this book. It essentially broadens the use and application of the classical block diagram technique that holds for zero initial conditions by its definition. The complete block diagram technique, being defined and developed for arbitrary initial conditions, fully overcomes the severe restriction of the classical block diagram technique.
Since Lyapunov stability properties are defined for nonzero initial conditions then their tests should be carried out by using F(s) because the use of G(s) can give the result opposite to the correct one, i.e. the result obtained via G(s) can be that the system is stable in spite it is unstable. The test via F(s) overcomes this problem.
BIBO stability was defined for zero initial conditions in order to test it effectively by using G(s). Initial conditions are almost always different from zero. Allowing nonzero initial conditions various new stability properties under boundedinput and for bounded arbitrary initial conditions are discovered and defined in this book. Their tests should be carried out by using F(s). G(s) is inapplicable.
For both Lyapunov stability properties and boundedinput and nonzero bounded initial conditions the new stability criteria proved in the book are in terms of F(s).
The book establishes the new system fundamental in the complex domain. It is inherent for the system stabilization and/or optimization. The discovers and the contributions of the book should essentially complete the university course in linear both control systems and dynamical systems. They open new avenues for research.
The book is equally significant and useful for lecturers, students, researchers as for linear dynamic system designers, control and system engineers.

Summary
Stability Domains is an uptodate account of stability theory with particular emphasis on stability domains. Beyond the fundamental basis of the theory of dynamical systems, it includes recent developments in the classical Lyapunov stability concept, practical stabiliy properties, and a new Lyapunov methodology for nonlinear systems. It also introduces classical Lyapunov and practical stability theory for timeinvariant nonlinear systems in general and for complex (interconnected, large scale) nonlinear dynamical systems in particular. This is a complete treatment of the theory of stability domains useful for postgraduates and researchers working in this area of applied mathematics and engineering.Videos
