摘要
本文利用多变量系统极点配置的结果,提出了一种具有指定闭环极点,并使二次型指标达到极小的次最优控制系统的设计方法,这种设计方法与标准线性二次型调节器(LQR设计方法的不同之点,就在于设计中引入了闭环极点约束,使闭环系统能具有希望的动态特性,本文还给出了在计算机上易于实现的设计算法和计算过程,以及设计实例。
Using the results of the multivariabe system pole assignment,we propose a method for designing sub-optimal control systems with the specified closed-loop poles dy minimizing the linear quadratic performance index in this paper. The difference between this method and the standard linear quadratic regulator design method is that the closed-loop poles assignment is considered in this design method so that the closed-loop system will have the desirable dynamical properties along with the minimal performance index. The algorithm and the computation steps implemented on computer easily, arc presented in this paper. The validity of the design algorithm is vcrficd by an example.
