| 摘 要： | 针对具有变结构且对象未知的单输入单输出的非线性系统模型的特点，基于自适应模糊，提出了一种具有投影功能的新型“扩张状态观测器”．该方法能有效跟踪变结构非线性系统的各阶状态变量，拓宽了非线性状态误差反馈控制器和自抗扰控制器的应用范围，同时给予了稳定性证明．最后，通过数值仿真验证了方法的可行性和有效性．

| Abstract: | By considering the special characteristics of an unknown disturbance and an unknown plant of single-input/output nonlinear variable structure systems, based on the fuzzy adaptive controller, a new method with the projection function for controlling the variable structure is presented. Because the method can track satisfactorily all types of state of a class of uncertain variable structure systems, it can extend the nonlinear state error feedback control law (NLSEF) and auto disturbance rejection controller (ADRC) application field. Furthermore, the proof of the stability of the method is made mathematically. Finally, three examples are given to demonstrate the method. |
