Geometric Theory of Reduction of Nonlinear Control Systems [PDF]

Computational Mathematics and Mathematical Physics, 2018
The foundations of a differential geometric theory of nonlinear control systems are described on the basis of categorical concepts (isomorphism, factorization, restrictions) by analogy with classical mathematical theories (of linear spaces, groups, etc.).

Theory of Fuzzy Chaos for the Simulation and Control of Nonlinear Dynamical Systems [PDF]

Applied Computational Intelligence, 2004
The authors propose several alternative definitions of fuzzy chaos and explore the advantages of each of these definitions. The authors apply these definitions to the problems of modelling, simulation, and control of nonlinear dynamical systems. They illustrate their approach with two cases: Chua's circuit and Duffing's oscillator.

Stability of fuzzy control systems by using nonlinear system theory

Annual Review in Automatic Programming, 1992
In 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.

An iterative learning control theory for a class of nonlinear dynamic systems

Automatica, 1992
Abstract 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

Finite-Time Synchronization of Fractional-Order Nonlinear Systems with State-Dependent Delayed Impulse Control

International Journal of Bifurcation and Chaos in Applied Sciences and Engineering
This paper delves into the topics of Finite-Time Stabilization (FTS) and Finite-Time Contractive Stabilization (FTCS) for Fractional-Order Nonlinear Systems (FONSs). To address these issues, we employ a State-Dependent Delayed Impulsive Controller (SDDIC)

Singular perturbation theory in control of nonlinear systems with uncertainties

2016 24th Iranian Conference on Electrical Engineering (ICEE), 2016
In this paper, a control approach is proposed for stabilization of nonlinear systems in the presence of both matched and unmatched uncertainties. By combining the time scale separation and backstepping, first, high-gain filters are designed to estimate the uncertainties, and then, a fast dynamical equation is derived which the solution is found to ...

Theory and Design of PID Controller for Nonlinear Uncertain Systems

IEEE Control Systems Letters, 2019
It 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, 1994
A 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.
