摘要: 介紹了一種基于系統特征數據的控制器設計算法.該算法僅根據被控對象的輸入、輸出采樣數據,按照卷積定理計算出被控對象的單位脈沖響應作為系統的特征數據;在控制量約束條件下,根據特征數據以最速響應為控制目標規劃出輸出參考數據和最速控制律;然后根據控制目標和最速控制律的要求計算出理想控制器的特征數據;最后,根據控制器的特征數據辨識出線性控制器參數.仿真結果表明,控制結果具有最速參考控制的特征.Abstract: A method is introduced for designing a controller based on the feature data of a control system. According to the input and output data of a controlled object only, this method identifies an impulse response by means of the convolution theorem. The impulse response data are taken as the feature data of the control system. With the controlling signal in a certain scope, the output reference data and the fastest control signal are calculated according to the feature data to meet the requirements of the fastest response.Then the ideal feature data of the controller are worked out on the basis of the control goal and the fastest control signal. Finally the linear parameters of the controller are identified by the feature data. Simulation results show that the control result has the characteristic of the fastest reference control.
