【摘要】 当主动隔振系统的被控参数为定常或变化较小时,采用一般常规反馈控制可以得到满意的控制效果,但当对象在运行过程中其结构与参数及环境有剧烈变化时,仅用常规的反馈控制技术无法满足控制要求.对某主动隔振系统从无控制、常规比例积分微分(PID)控制以及基于PID的模型参考自适应控制3种情况进行了研究,提出了在主动隔振系统中采用的控制方法.仿真结果表明,基于PID的模型参考自适应控制方法能够很好地跟踪参考模型的输出,具备较强的抗干扰能力.更多还原

【Abstract】 Only if the controlled parameter of an active vibration-isolated system is a constant or with small variation,it is effective to apply the conventional feedback control.Thus,this does not work when the object structure,parameter and environment are abruptly changed.In comparison with such methods as passive control,traditional PID control and PID-model-referenced adaptive control,a control method is selected for an active vibration-isolated system.To this end,it is found from simulation results that the PID-model-referenced adaptive control method can efficiently track referenced model outputs and possesses high anti-interference ability.更多还原
