研究了μ理论在电液负载模拟器中的应用。提出了电液负载模拟器的鲁棒控制策略。电液负载模拟器是一个复杂的机-电-液复合系统，且是一个强耦合、时变受控对象。综合考虑参数摄动、模型摄动和外界干扰等不确定性因素，摘要应用μ综合理论设计了电液负载模拟器的鲁棒力控制器。通过对采用鲁棒力控制器的系统μ值的分析，分析了系统的鲁棒稳定性和鲁棒性能。最后，给出了鲁棒力控制器和经典力控制器的实验结果。仿真结果表明，所设计的鲁棒力控制器是有效的，具有优越性
Application of mu theory in the electrohydraulic load simulator is studied. Robust control strategy of the electrohydraulic load simulator is put forward. The electrohydraulic load simulator is a complicated mechanical-electronic-hydraulic compound system, moreover it is a strong coupling and time-varying controlled object. Synthetically considering uncertainties such as parameter perturbations, model perturbations and external disturbances etc., robust force controller of the electrohydraulic load simulator is designed using mu synthesis theory. Robust stability and robust performance are analyzed by mu values of the system in which robust force controller is used. Moreover, experiment results of systems using robust force controller and classical force controllers are shown. The results indicate that the designed robust force controller is efficiency and superiority
