摘要
研究了存在未知外部干扰时的互质因子摄动系统的鲁棒稳态追踪问题.利用Youla参数化方法,提出了一个最坏情况稳态绝对误差的精确计算公式.该公式使得最优稳态跟踪控制器设计问题等价于保证系统鲁棒稳定时l1的最优鲁棒控制器设计问题.
The robust steady-state tracking problem subjected to coprime factor perturbations and unknown external bounded disturbance is addressed. An exact formula for computing the worst-possible steady-state absolute value of the control error is proposed by using Youla parameterization. With this formula, it is shown that the design of optimal robust steady-state tracking controller is reduced to l1 optimal robust controller design ensuring robust stability.
