摘要

摘要: 根据弹支干摩擦阻尼器的特点,提出弹支干摩擦阻尼器控制转子振动的方案,建立了基于主动弹支干摩擦阻尼器的比例积分控制(PI控制)和连续增益调度比例积分控制(连续GSPI控制)方法,对两种控制方法控制转子通过临界转速的振动进行了理论分析、数值仿真和试验验证,并分析了其特点.

Abstract: A proportional integral (PI) controller and continuous gain scheduling proportional integral (GSPI) controller for active control of rotor vibration were developed,according to the characteristics of elastic support/dry friction damper (ESDFD).The theoretical analyses and numerical simulation results show that it is very effective to reduce rotor vibration around the first critical speed by using these control algorithms.Moreover,the continuous GSPI controller has the advantage of giving a well-behaved rotor run-up while maintaining the efficient controlled behavior to attenuate the amplitude of vibration of the first critical speed.
