摘要 提出一种不受稳定区域限制的广域阻尼鲁棒H2/H∞控制方法。首先采用完全调节法获取可调节系统阻尼大小的状态反馈矩阵,在此基础上,考虑系统参数和外界扰动等不确定性因素,设计基于完全调节法的混合H2/H∞多目标鲁棒控制策略。以IEEE 4机11节点系统作为测试对象进行时域仿真,结果表明,该控制策略在阻尼性能和鲁棒性能方面均较传统的H2/H∞控制策略有明显优势。 A strategy of wide-area damping robust H2/H∞ control strategy is proposed,which is not restricted by the stable region.The perfect regulation is applied to obtain the state feedback matrix with adjustable damping coefficients,based on which,a complex H2/H∞ control strategy considering the uncertainties of system parameters and external disturbances is designed.Time-domain simulation is carried out for IEEE 4-generator 11-bus system and results show that,compared with the traditional H2/H∞ control strategy,it is much better in both damping performance and robustness performance.
