چکیده

This paper deals with the digital control of a particular class of non-linear singularly perturbed (NLSP) systems. Three distinct multi-rate composite control strategies are discussed. In the ® rst case, it is assumed that measurements of the slow and fast variables are scheduled at the same fast sampling period nd . Then, multi-rate measurements are considered and two di€ erent strategies are presented. The paper ends with an academic example and simulations.

The asymptotic expansion for a class of non-linear singularly perturbed problems with optimal control

In this article, we discuss a class of three-dimensional non-linear singularly perturbed systems with optimal control. Firstly, we confirm the existence of heteroclinic orbits connecting two equilibrium points about their associated systems by necessary conditions of optimal control and functional theory. Secondly, we study the asymptotic solutions of the singularly perturbed optimal control pr...

Fuzzy H-infinity Output Feedback Control Design for Singularly Perturbed Systems: An LMI Approach

This paper examines the problem of designing an H∞ output feedback controller for a class of nonlinear singularly perturbed systems described by a TakagiSugeno (TS) fuzzy model. Based on a linear matrix inequality (LMI) approach, we develop an H∞ output feedback controller which guarantees the L2-gain of the mapping from the exogenous input noise to the regulated output to be less than some pre...

Model Predictive Control of Nonlinear Singularly Perturbed Systems: Application to a Large-Scale Process Network

This work focuses on model predictive control of nonlinear singularly perturbed systems. A composite control system using multirate sampling (i.e., fast sampling of the fast state variables and slow sampling of the slow state variables) and consisting of a “fast” feedback controller that stabilizes the fast dynamics and a model predictive controller that stabilizes the slow dynamics and enforce...

Control Design for Uncertain Singularly Perturbed Systems with Discrete Time Delay

The problem of state-feedback control design for a class of singularly perturbed systems with time delays and norm-bounded nonlinear uncertainties is studied in this paper. The system under consideration considers discrete delays in both slow and fast dynamics and norm-bounded nonlinear uncertainties. It is shown that the control gains are obtained to guarantee the stability of the closed-loop ...

Robust H∞ State-Feedback Control Design for Fuzzy Singularly Perturbed Systems with Markovian Jumps: An LMI Approach 175 Robust H∞ State-Feedback Control Design for Fuzzy Singularly Perturbed Systems with Markovian Jumps: An LMI Approach

This paper examines the problem of designing a robust H∞ state-feedback controller for a class of uncertain Markovian jump nonlinear singularly perturbed systems described by a Takagi-Sugeno (TS) fuzzy model with Markovian jumps. Based on a linear matrix inequality (LMI) approach, LMI-based sufficient conditions for the uncertain Markovian jump nonlinear singularly perturbed systems to have an ...
