摘要
讨论了互质因子摄动系统的鲁棒稳定性和性能敏感性问题,给出了互质因子摄动系统鲁棒稳定的一个充分条件,并得到了用H∞范数测量的系统敏感函数矩阵和闭环传递函数矩阵的上限。
In this paper, the robust stability and the performance sensitivity of the closed loop system with left coprime factor perturbations on the plant and right coprime factor perturbations on the controller are investigated.A sufficient condition is given for the robust stability of the perturbed system, and the upper bounds measured by the H ∞ norm for the senstivity function matrix and the closed loop transfer function matrix are also presented.The perturbed structure considered here is more representative, therefore our work here is of universal significance.
