基于时间最优控制的模糊控制优化方法

讨论了二次积分系统的时间最优控制．考虑到系统的鲁棒性和抗扰动能力，对其参数设计方法进行了改进．理论分析和仿真表明，这种基于时间最优控制的非线性设计方法具有很好的控制效果和鲁棒性，适用于一类二阶系统的控制．通过二阶系统的模糊控制和时间最优控制的对比发现，一类二阶系统或可近似为二阶系统的模糊控制实际上是对二阶系统最优控制的一种近似．在此基础上，指出了模糊控制规则设计中一种常见的错误，并提出了基于时间最优控制的模糊控制规则的制定和优化方法

Optimization Method of Fuzzy Control Based on Optimal Control

The optimal control of second order integral system was discussed. Considering the robustness and disturbance, a new kind of parameter design method of optimal controller was proposed. The simulation results show that this method is effective and successful with strong robustness, and can also be used to some other linear or nonlinear second order systems. Comparing fuzzy control with optimal control, it is found that the fuzzy control of a class of second order systems is actually a near optimal control. Based on it, common errors of fuzzy control were pointed out, and a new kind of design and optimization method of fuzzy control was presented.
