一般系统的鲁棒性优化设计

讨论了线性定常多变量一般系统(包括可稳系统和可控系统),在时域上用状态反馈来设计鲁棒系统的问题.用状态反馈配置系统极点时有一定的自由度.文中分析了可稳系统用状态反馈,配置系统极点时有一定的自由度的内在因素,并论证给出了一个反映系统鲁棒性的性能指标,还提出了一种设计鲁棒系统控制器的数值计算方法.

Robustness Optimization Method for General Systems

This paper discusses the problem of designing the rubust systems forgeneral time invariant multivariable systems under state feedback.The systemscan be stabilizable or controllable.In multi-input systems,there is some degreeof freedom for pole assignment using state feedback.This paper investigates theinherent reason for the existance of degree of freedom in pole assignment forstabilizable systems,which include controllable ones.In this paper,a performanceindex related to robustness is formulated,and a computing method is given for thedesign of robust controllers.Examples and simulation results show that designedthe systems using paper's method are rubust against parameter perturbation andhave good instantaneous responses.
