摘要
电梯运行中导轨不平引起的水平振动会影响舒适性。为了有效抑制电梯振动,以音圈电机为作动器,使用振动主动控制,建立音圈电机和电梯水平振动的数学模型。布置传感器和作动器的位置,将位移、速度和加速度的比例反馈组合为PID控制器,使用Matlab/Simulink对控制器进行参数整定;并对电梯水平振动主动控制系统进行仿真分析。仿真结果表明在共振频率处的振动位移得到大幅抑制,同时随机振动激励下的振动位移有明显减小。
Horizontal vibration of elevator caused by rail flatness influences the comfort. To suppress the vibra-tion of elevator, voice coil motor was used as actuator in vibration active control. Voice coil motor and horizontal vi-bration was analyzed and modeled. Position of sensor and actuator was assigned. Proportional gain feedback controlof position, speed and acceleration were combined into PID controller. Horizontal vibration control system was sim-ulated with Matlab/Simulink. The result showed the vibration displacement on harmonic frequency was suppressedsharply and vibration displacement by random vibration obviously reduced.
