现代控制理论中的特征结构配置法(Eigenstructure Assignment),揭示了线性定常系统状态反馈控制规律的设计能力,并向设计者提供了充分的设计自由度。本文介绍了一种利用特征结构配置法进行输出反馈控制器设计的算法。当n阶r个输入m个输出的线性定常系统满足关系r+m>n时,运用该算法可以获得配置任意希望闭环特征值集合的线性输出反馈控制规律,并具有一定的特征结构配置自由度;对于不满足r+m>n的系统,利用积分器增广可以获得比Luenbetger状态估计器阶数低的动态输出反馈控制器,以实现闭环特征值任意配置。该算法容易用数字计算机编程实现。
The Eigenstructure Assignment in modern control theory reveals the design capability of the state feedback control law of linear steady-state systems and provides the designer with sufficient design freedom. In this paper, an algorithm of output feedback controller design based on feature structure configuration is introduced. The linear output feedback control law can be obtained by using this algorithm when the linear steady-state system with r inputs and r outputs of n-order r satisfies the relationship r + m> n. The control law of the linear output feedback with a set of arbitrary closed- For systems that do not satisfy r + m> n, dynamic output feedback controller with lower order than Luenbetger state estimator can be obtained by using integrator augmentation to realize arbitrary configuration of closed-loop eigenvalues. The algorithm is easy to use digital computer programming.
