The invention discloses a drive control system for an elevator. The drive control system comprises a car speed controller, a flexible suspension part controller and a drive motor controller. The lift car speed controller takes the lift car as a controlled object, takes a lift car speed tracking error obtained by subtracting lift car speed feedback from a lift car speed instruction as input, and outputs a lift car tension instruction applied to the lift car by the flexible suspension part; the flexible suspension part controller takes the flexible suspension part as a controlled object, takes a pull force tracking error obtained by subtracting a lift car pull force feedback value from a lift car pull force instruction as input, and outputs a speed instruction of a driving motor; and the driving motor controller performs speed regulation control on the driving motor, so that the speed feedback value of the driving motor tracks the speed instruction. According to the invention, high-performance direct control of the moving speed of the elevator car can be realized.
本发明公开了一种用于电梯驱动控制系统,包括轿厢速度控制器、柔性悬挂件控制器和驱动电机控制器;所述轿厢速度控制器以电梯轿厢为被控对象,以电梯轿厢速度指令减去电梯轿厢速度反馈得到的轿厢速度跟踪误差为输入,输出柔性悬挂件施加给电梯轿厢的轿厢拉力指令;所述柔性悬挂件控制器以所述柔性悬挂件为被控对象,以轿厢拉力指令减去轿厢拉力反馈值得到的拉力跟踪误差为输入,输出驱动电机的速度指令;所述驱动电机控制器对驱动电机进行调速控制,使其速度反馈值跟踪所述速度指令。本发明能实现对电梯轿厢移动速度的高性能直接控制。
