Theory of chaos and control in a nonlinear optical system
Physics Letters A, 1994A parametric amplifier driven by a periodically pulsed pump field inside a cavity containing a Kerr nonlinearity may be modeled mathematically by a two-dimensional map. We investigate control of chaotic solutions of this model system using the OGY method.

Theory and Design of PID Controller for Nonlinear Uncertain Systems
IEEE Control Systems Letters, 2019It is well-known that the classical proportional-integral-derivative (PID) controller plays a fundamental role in various engineering systems. However, up to now a theory that can explain the rationale why the linear PID can effectively deal with nonlinear uncertain dynamical systems and a method that can provide explicit design formula for the PID ...

THE NEW RESULTS IN THE THEORY OF PERIODIC OSCILLATION IN NONLINEAR CONTROL SYSTEMS
IFAC Proceedings Volumes, 1990Abstract The ordinary systems and the systems including elements of new kind (to describe these elements the new mathematical methods have been developed) was studied. In this paper we state some new results about periodic oscillations: existence of oscillations, number of distinct conditions, stability conditions, new numerical procedures for ...

Event-Triggered Global Finite-Time Control for a Class of Uncertain Nonlinear Systems
IEEE Transactions on Automatic Control, 2020This paper focuses on the problem of global finite-time stabilization for a class of uncertain nonlinear systems with event-triggered inputs. The existing event-based design methods can only partially compensate for the effects of the event-triggered ...

Theory of cone methods for null controllability of nonlinear control systems
IEEE Transactions on Automatic Control, 1979Cone-valued Lyapunov functions have been used by several authors to examine the stability of nonlinear systems. However, the general problem of constructing a suitable cone given the nature of nonlinearity seems to be as difficult as that of constructing a suitable Lyapunov function.

Toward a nonequilibrium theory for nonlinear control systems [PDF]
, 2007 This paper is concerned with the development of basic concepts and constructs for a nonequilibrium theory of nonlinear control. Motivated by an example of nonstabilizability of rigid spacecraft about an equilibrium (reference attitude) but stabilizability about a revolute motion, we review recent work on the structure of those compact attractors which ...
