时变时滞模糊系统的时滞反馈控制
Delayed Feedback Control for Continuous-Time Fuzzy Systems with Time-Varying Delay
摘要
Abstract
The delayed feedback control problem is studied for a class of continuous-time fuzzy systems with time-varying delay. Based on a new fuzzy Lyapunov-Krasovskii functional (LKF), a delay-dependent stability criterion is derived for the open-loop fuzzy systems. Less conservative results are obtained by considering the additional useful terms when estimating the upper bound of the derivative of LKF and introducing new fuzzy free weighting matrices. Then based on parallel distributed compensation (PDC), a delay-dependent stabilization condition is derived in terms of linear matrix inequalities (LMIs) and the corresponding controller can be obtained by solving a set of LMIs. Finally, simulation examples show the effectiveness of the proposed method.关键词
