摘要:

研究μ理论在电液负载模拟器中的应用,提出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。综合考虑参数变化、模型变动和干扰等不确定性的影响,利用μ综合控制理论设计电液负载模拟器的鲁棒力控制器,并通过μ分析使用鲁棒力控制器时系统的鲁棒稳定性和鲁棒性能。给出使用鲁棒力控制器和经典力控制器时的实验结果,实验结果表明所设计鲁棒力控制器的有效性和优越性。

Abstract:

Application of μ 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 μ synthesis theory.
