Whoever had found his way to the tavern’s block
Would have to be insane if on another door knock
Fate never crowned any with drunkenness, except
The one who considered this the highest luck.
Whoever finds his way into the tavern
From the bounty of the wine, temple’s secrets unlock.
He who read the secrets of this wine,
Found the secrets in the dust upon which we walk.
Only seek the obedience of the insane
In our creed, logic and sanity we mock.
My heart asked not for longevity of beauty
Because sadly this is the way of the clock.
From the pain of the fading morning star at dawn
I cried so much that I saw the moon, though Venus my eyes struck.
Who talks about the story of Hafiz and his cup?
Why would the king know where the policemen flock?
Praise the King who considers the nine heavens
A mere crevice in His courtly block.
تحلیل و کنترل سیستمهای غیر خطی
This is the first book on a hot topic in the field of control of nonlinear systems. It ranges from mathematical system theory to practical industrial control applications and addresses two fundamental questions in Systems and Control: how to plan the motion of a system and track the corresponding trajectory in presence of perturbations. It emphasizes on structural aspects and in particular on a class of systems called differentially flat. Part 1 discusses the mathematical theory and part 2 outlines applications of this method in the fields of electric drives (DC motors and linear synchronous motors), magnetic bearings, automotive equipments, cranes, and automatic flight control systems. The author offers web-based videos illustrating some dynamical aspects and case studies in simulation (Scilab and Matlab)

This volume is intended for researchers in engineering and applied mathematics. It can also be used as a textbook for gradute students dealing with non-linear systems and control theory. After a self-contained treatment of the differential-geometric prerequisites, the book deals with controlability and observability properties of nonlinear systems, as well as various ways to obtain input-output representations. Problems of transforming nonlinear systems into simpler forms are discussed, including feedback linearization problem. The disturbance and input-output decoupling problems are treated in detail, as well as some aspects of feedback stabilization, interconnection and inversion of nonlinear systems. Emphasis is put on fundamental notions as (controlled) invariant distributions and submanifolds, together with algorithms for computing the required feedbacks. Extensions of these methods to other sysnthesis problems are indicated in the exercises at the end of each chapter. Special attention is paid to mechanical nonlinear control systems, and finally the theory is extended to general continuous-time and discrete time systems. Numerous examples and exercises illustrate the main results of the book
