【摘要】:考虑在满足预设性能前提下的含未知参数极值搜索系统的控制问题,针对含未知参数的目标函数设计极值参考轨迹,利用性能函数进行预设性能设定,利用误差转换函数构建等效模型并针对等效模型设计反演控制器,设计未知参数的自适应估计律,使系统实现极值搜索的同时满足预设性能。仿真验证了该方法的有效性。
[Abstract]:Considering the control problem of the extremum search system with unknown parameters under the premise of satisfying the presupposition performance, the extremum reference trajectory is designed for the objective function with unknown parameters, and the performance function is used to set the default performance. The equivalent model is constructed by using the error conversion function and the inversion controller is designed for the equivalent model. The adaptive estimation law of unknown parameters is designed to make the system realize the extremum search and satisfy the preset performance. The effectiveness of the method is verified by simulation.
