【摘要】:考慮在滿足預(yù)設(shè)性能前提下的含未知參數(shù)極值搜索系統(tǒng)的控制問題,針對(duì)含未知參數(shù)的目標(biāo)函數(shù)設(shè)計(jì)極值參考軌跡,利用性能函數(shù)進(jìn)行預(yù)設(shè)性能設(shè)定,利用誤差轉(zhuǎn)換函數(shù)構(gòu)建等效模型并針對(duì)等效模型設(shè)計(jì)反演控制器,設(shè)計(jì)未知參數(shù)的自適應(yīng)估計(jì)律,使系統(tǒng)實(shí)現(xiàn)極值搜索的同時(shí)滿足預(yù)設(shè)性能。仿真驗(yàn)證了該方法的有效性。
[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.
