【摘要】 本文讨论具有鲁棒稳定性和抗持续有界扰动的控制器的设计。提出了一种新的综合灵敏度指标函数。这种指标函数既可用于单变量系统,也可用于多变量系统,通过权系数的选择。设计者可对鲁棒性和抗扰动性进行灵活地加权,并绐出了把这种L’综合指标优化设计问题转化为一般L’优化总理求解的方法。更多还原

【Abstract】 The problem discussed in this paper is the design of a mixed scnsitivity minimization controller,which has robust stability and can optimally reject all persistant bounded disturbances.A new probem of mixed scnsitivity minimization is formulated.The new index function presented is suitable for both SISO and MIMO systems By the choice of weighting coefficients.The designer can weight robustness or the capsbility of rejection disturbance flexibly.A method is grvcn which solves the 1’ mixed index optimization design problem by translating this kind problem into normal l’ optimization design problem.更多还原
