基于模糊动态模型的非线性控制器综合与分析

Synthesis and Analysis of Nonlinear Controller Based on Dynamic Fuzzy model

基于控制对象的模糊动态模型,分别给出了连续和离散情形下的非线性状态反馈控制器的设计方法,并对其稳定性进行了分析,得到了确保系统全局稳定的充分条件。该方法将传统的模糊控制器中的加权系数视为非线性增益,使得控制器的设计更为灵活。通过仿真算例,验证了所提方法的有效性。

Based on the dynamic fuzzy model, which represents the plant, the design and the stability analysis of nonlinear state feedback controller were presented in both the continuous time case and the discrete time case. And the stability of the closed loop was analyzed. Sufficient conditions which guarantee the stability were obtained. The simulation results show the validity of the new method.
