The problem of robust H∞ fuzzy state feedback and dynamic output feedback control for uncertain fuzzy descriptor systems is discussed. In the case that time-varying uncertainties are in all parameter matrices except E, sufficient conditions for the existence of fuzzy state feedback and dynamic output feedback robust H∞ controllers are given in terms of LMI. The fuzzy state feedback control law ...

This paper focuses on the hybrid output-feedback guaranteed cost H∞ robust control problem for a class of uncertain linear systems. Time-varying uncertainties are contained in both the state matrix and input matrix. Suppose there exist a finite number of candidate controllers with known controller gain matrices and none of the controllers can solve the guaranteed cost H∞ robust control problem....

Abstract Under the multi-objective framework, this paper presents a hybrid algorithm to solve robust static output feedback control problem for continuous polytopic uncertain system. To obtain static output feedback gain, a new hybrid algorithm is proposed by combination of a hybrid algorithm of the Particle Swarm Optimization (PSO) and Differential Evolution (DE), and the linear matrix inequal...

In this paper, we propose a design method for a robust adaptive output feedback control system for uncertain MIMO nonlinear systems with a higher order relative degree and an uncertain controlled system order. By using a virtual input filter method, this method allows an adaptive output feedback control of MIMO nonlinear systems without constructing a state observer in the controller. Copyright...
