摘要
本文利用模糊逻辑连续滑模控制方法,研究了非线性Willis混沌系统的受控问题。设计基于模糊逻辑的模糊控制器,通过隶属函数将滑模面切换函数模糊化,再采用质心法解模糊控制器的输出。用此方法使系统输出跟踪一个给定的状态目标,最终使跟踪误差趋于零,仿真结果验证了方案的有效性。
In this paper we propose the fuzzy logic sliding control method, and then apply to the control of Willis chaos system. We design fuzzy logic controller. By membership function, we may fuzzify the switch function of slide sphere, and obtain the output by centroid defuzzified controller. Based on this method, the system output could track a given target, and make the track error to zero. Simulation results indicate the valid of method.
