摘要: 本文提出了采样控制系统对象模型的一种快速辨识方法——方块脉冲响应序列法,继而将辨识的结果用于一种快速仿真方法——时域矩阵法中,以获取系统的时域响应和口标函数,并使用单纯形法反复调用该目标函数以对控制器参数进行优化,从而大大加速了寻优过程,节约了计算机时。Abstract: This paper presents a high-speed identification method - the square pulse response sequence method - for identifying the object model of sample control systems.The result obtained by this method is then employed in the high-speed simulation method (the time domain matrix method) to obtain the time domain response and cost.function of the system. The cost function is repeatedly called by a program derived from the simplex method, to optimize. the controller parameters. Thus theprocess of optimization is greatly expedited and the total computer timereduced.
