摘　　要：为了解决传统增益稳定设计方法无法抑制输入干扰及鲁棒性较差的问题,提出了一种基于相位稳定的鲁棒控制策略。首先,引入第二相位裕度设计相位稳定控制器;其次,为了保证模型参数摄动后系统的鲁棒性能,给出了一种根据鲁棒性能条件优化控制器参数的方法;最后,通过仿真验证了所提策略的有效性,结果表明所设计的控制器可以有效抑制输入干扰并满足摄动系统鲁棒性能要求。A phase-stable robust controller design method is proposed to address the issues of traditional gain-stabilized design methods being unable to suppress input interference and having poor robustness.Firstly,the second phase margin is introduced to design the phase-stabilized controller.Secondly,to ensure the robust performance of the system after the model parameters are ingested,a method is given to optimize the controller parameters according to the robust performance condition.Finally,the effectiveness of the proposed strategy is verified by simulation,and the results show that the designed controller can effectively suppress the input disturbances and meet the robust performance requirements of the ingestion system.
