摘要
在现代城市生活中,电梯作为高层建筑物内主要的垂直运输工具,在日常的人员输送、货物运输等各方面发挥着重要的作用,为了降低高速电梯的水平振动,建立了基于六自由度的电梯轿厢水平振动主动控制的动力学模型,给出了其微分方程。同时提出了一种液压主动导靴的结构,并分析了其控制原理。通过仿真研究表明,液压主动导靴采用自适应模糊控制策略,其性能优于PID控制策略和模糊控制策略,能明显降低电梯水平振动加速度值,从而达到减振的目的。
In modern urban life,elevators are the main vertical transport of high-rise buildings.In the daily personnel carries,cargo transport and other aspects,elevators play an important role.In order to reduce the horizontal vibration of high-speed elevator,a dynamic model for active control of horizontal vibration is established based on 6 DOF,and the differential equations are also given.Then a kind of hydraulic active guide shoe sketch is put forward,and its control principle is analyzed as well.The simulation results show that the hydraulic active guide shoe adopts adaptive fuzzy control strategy,which performance is better than PID control strategy and fuzzy control strategy,and the horizontal vibration acceleration value of elevator is reduced significantly.Thus the vibration reduction is achieved.
