A Controllability Theory for Nonlinear Systems
IEEE Transactions on Automatic Control, 1971A Lyapunov-like approach to the controllability of nonlinear dynamic systems is presented. A theory is developed which yields sufficient conditions for complete controllability for some classes of nonlinear systems; feedback controllers which drive the systems to desired terminal conditions, at a specified final time, are also obtained.

Modeling Control and Forecasting Nonlinear Systems Based on Grey Signal Theory
International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2023Based on this article, a fuzzy NN (neural network) based on the EBA (evolved bat algorithm) was developed to devise adaptive control with gray signal prediction to provide asymptomatic stability and increased driving comfort. The method is used to assess plant nonlinearity and to perform structural tracking of the signal.

Stability of fuzzy control systems by using nonlinear system theory
Annual Review in Automatic Programming, 1992In this paper we consider fuzzy control system as nonlinear control systems. We present an unifying framework of methodologies and summarize three different methods. The first one is based on the geometrical interpretation of the system dynamic behaviour in the phase portrait.

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 ...

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.

Differential Systems and Nonlinear Control Theory
IFAC Proceedings Volumes, 1995Abstract Techniques from exterior differential systems provide a powerful geometric tool for the study of nonlinear systems. This paper presents a sketch of the relevant ideas and indicates both the ways in which they have already made an impact in control as well as some areas of future application.

An iterative learning control theory for a class of nonlinear dynamic systems
Automatica, 1992Abstract An iterative learning control scheme is presented for a class of nonlinear dynamic systems which includes holonomic systems as its subset. The control scheme is composed of two types of control methodology: a linear feedback mechanism and a feedforward learning strategy. At each iteration, the linear feedback provides stability of the system

On the theory of nonlinear control systems
2005A review of some of the recent advances in nonlinear control theory is presented. A central theme in the discussion is the notion of state feedback and its use for altering the structural properties of a system. The relations between various synthesis problems, controlled invariance and a general decomposition problem are investigated.

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 ...
