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
The time optimal control of quadratic integral system is discussed. Considering the robustness and anti-disturbance ability of the system, the parameter design method is improved. Theoretical analysis and simulation show that the nonlinear design method based on time optimal control has good control effect and robustness and is suitable for the control of a class of second-order systems. By comparing the fuzzy control of second order system and the optimal control of time, it is found that the fuzzy control of a kind of second order system or approximate second order system is actually an approximation to the optimal control of second order system. Based on this, a common mistake in the design of fuzzy control rules is pointed out, and the method of formulation and optimization of fuzzy control rules based on time optimal control
