针对一类多输入极值搜索系统的预设性能控制问题,首先,利用目标函数设计出状态量极值参考轨迹;然后,利用性能函数和误差转换函数构建等效模型,分别针对单输入系统进行预设性能控制器设计;最后,从反演控制的角度逐步选取适当的李雅普诺夫函数设计不确定参数自适应估计律.该方法结构简单,容易实现,使系统在满足预设性能的前提下完成了极值搜索过程,数学仿真验证了方法的可行性.
Aiming at the problem of preset performance control of a multi-input extreme value search system, firstly, an extreme value state reference trajectory is designed by using the objective function. Then, an equivalent model is constructed by using the performance function and error conversion function, Finally, from the point of view of inversion control, we select the appropriate Lyapunov function to design the adaptive estimation law of uncertain parameters step by step. The proposed method is simple in structure and easy to implement, which makes the system meet the preset performance Finished the extremum search process, the mathematical simulation verified the feasibility of the method.
