具有相对稳定性的线性调节器设计

在传统的线性二次型问题中,一般是通过试错法选择加权矩阵来获得良好的动态响应。本文将极点配置方法和二次型设计技术结合起来,提出了一种具有相对稳定性的最优控制系统设计方法,由此得到的闭环控制系统具有极点配置方法和二次型设计技术两者的优点。最后,用一个算例说明这种设计过程的有效性。

DESIGN OF LINEAR REGULATORS WITH RELATIVE STABILITY

In the classical linear quadratic problems, weighting matrices are usually choosed on trial and error to get good responses. In this paper,a design method for optimal control systems with relative stability is proposed by combining the pole assignment method with the quadratic design technique. The gained closed-loop control systems have the merits of both a pole assignement problem and a quadratic design. In the end,an illustrative example is presented to demonstrate the effectiveness of the design procedure.
