摘　　要：地铁屏蔽门作为城轨交通的重要部分,无刷直流电机是主要的执行机构。在屏蔽门控制中存在速度慢、易干扰、效率低。该文提出了速度环模糊参数自适应PID算法。建立模型并搭建双闭环控制系统。通过实验得出:在模糊参数自适应PID算法的控制下,速度曲线基本没有超调;与稳态误差相比,参数自整定算法的稳态误差为2.7%;参数自适应算法控制系统具有响应速度快、动静态性能好、自适应性能好、系统鲁棒性强且运行平稳,在地铁屏蔽门控制中的控制效果更佳。Subway platform screen door is an important part of urban rail transit,and brushless DC motor is the main actuator.In the screen door control,there are slow speed,easy interference and low efficiency.This paper proposes a fuzzy parameter adaptive PID algorithm for speed loop.Establish a model and build a double closed-loop control system.Through experiments,it is concluded that under the control of fuzzy parameter adaptive PID algorithm,the speed curve basically has no overshoot,compared with the steady-state error,the steady-state error of the parameter self-tuning algorithm is 2.7%.The parameter adaptive algorithm control system has fast response speed,good dynamic and static performance,good adaptive performance,strong system robustness and stable operation,and has better control effect in subway platform screen door control.
