摘要
安全门系统中大多采用经典比例-积分-微分控制算法控制无刷直流电机,由于算法本身的缺陷使得安全门系统控制精度偏低。针对目前安全门系统中无刷直流电机的控制算法精度低问题,提出基于线性二次最优控制方法,采用计算机软件对安全门门体运行过程状态进行仿真,并对两种算法进行仿真对比研究。通过运动曲线对比与仿真数据分析可得,基于线性二次最优的站台安全门系统控制策略具有更高的精确性、可靠性和动态响应性能。
Most of the safety gate system uses the classic proportional-integral-derivative control algorithm to control the brushless DC motor.Because of the defect of the algorithm itself,the control accuracy of the safety gate system is low.Aiming at the problem of low accuracy of brushless DC motor control algorithm in safety gate system,this paper proposes a new method based on linear quadratic optimal control method.The computer software was used to simulate the running process of safety gate.Simulation results were compared with the two algorithms.According to the comparison of motion curves and simulation test data,the control strategy based on linear quadratic optimal platform security gate system has higher accuracy,reliability and dynamic response.
