研究了一类带有执行器饱和的模糊T-S时滞系统的稳定性控制问题,在设计过程中,运用平行分布补偿算法(PDC)建立了模糊控制器,应用Lyapunov函数以及线性矩阵不等式(LMI)方法,给出并证明了在含有执行器饱和情况下的T-S模糊时滞系统稳定性的充分条件,并且给出了模糊控制系统在含有外界干扰情况下的H∞控制性能指标。在仿真结果中进一步证明了所提出方法的有效性。
The robust stabilization problem was studied for a class of fuzzy Takagi-Sugeno (T-S) time-delay system with actuator saturation. By using the fuzzy parallel distributed compensation (PDC) approach, a fuzzy controller was developed, and the stabilization sufficient conditions were given and proved based on the Lyapunov function theory and linear matrix inequalities (LMIs). In addition, the H∞control performance target was also suggested as the fuzzy control system was interfered with something outside. Finally, simulation results are provided to verify the effectiveness of the proposed approach.
