具有双重不确定性非线性系统输出反馈鲁棒控制

摘要

The non-linear systems with parameter uncertainty and stochastic noise is studied in this paper. The indirect-type output feedback controller is formed via expending state vector. T-S fuzzy theory, linear matrix inequality (LMI) technique and parallel distribution compensation (PDC) structure are used to suggest the design method of robust fuzzy controller with dual uncertainity and non-linear system. With the inverted pendulum system as the controlled object, the simulation results indicate the effectiveness of -the proposed method.%对同时具有参数不确定性和随机干扰的非线性系统,通过扩展状态向量,构造间接型输出反馈控制器,运用T-S模糊理论、线性矩阵不等式(LMI)技术和并行分布补偿(PDC)结构,提出了具有双重不确定性非线性系统的鲁棒模糊控制器设计法.以倒立摆系统为被控对象,仿真结果验证了所设计方法的有效性.
