基于鲁棒稳定多项式摄动界理论的发电机线性反馈控制器综合分析

摘要

利用鲁棒稳定多项式单向摄动界的有关成果，解决了系统增益确定问题和D域鲁棒稳定性分析问题。在改进发电机综合线性反馈控制器设计方案的同时，指出了参数的鲁棒稳定摄动范围。实例计算表明，单向摄动界法较劳斯判据法更为快速、精确。%Based on the perturbation bounds theorems for the robust stability of polynomials, this paper proposes a way to determine the system's proper gain and to analyze robust D-stability of this controller. The corresponding algorithm is applied to the design of linear feedback controller, and perturbation bounds of the controller parameter are derived. An example shows that the result by the perturbation bounds method is superior to that of the Routh Criterion.
