摘要: 本文介绍一种计算多变量线性系统输出反馈控制器的算法.本算法首先计算具 有二次型性能指标的全状态反馈增益,然后用罚函数法确定输出反馈增益的初始 值,最后用Fletcher-Reeves共轭梯度法求得最优输出反馈控器参数.文中附有钢 丝滚球实验装置的输出反馈控制系统计算实例及所构成的实时控制系统的响应曲 线.Abstract: An algorithm for designing output feedback controller of a linear multivariable system is presented in this paper. Full state feedback gain with quadratic index is first computed. Penalty weight method is then used to determine the initial value of the output feedback control. And finally, parameters of the optimal output feedback controller are determined by Fletcher-Reeves conjugate gradient method Computation results of the algorithm and the performance of a real time control system based on the results are also given.
