    摘要:

    针对一类含不确定参数的严格反馈型极值搜索系统的控制问题,将极值搜索方法和反演(Backstepping)控制方法相结合,设计出系统状态的极值参考轨迹,利用 Backstepping控制方法逐步递推选取适当的 Lyapunov函数设计控制器和不确定参数自适应估计律,实现目标函数的极值搜索。仿真表明所提出控制器设计方法的有效性。

    Abstract:

    To solve control problems of strict-feedback extremum seeking systems with uncertain parameter, extremumseeking control method and Backstepping control method were combined. System state extremum reference trajectory wasdesigned. Backstepping controller and uncertain parameter adaptive estimation law were designed based on the appropri.ate Lyapunov functions selected by recurrence method, objective function extremum seeking was realized. Simulation re.sult showed that the proposed controller design method was effectiveness.
