摘要
文中针对小型空轨车辆的牵引传动控制系统方案和牵引电机控制算法进行分析,首先搭建了小型空轨车辆的控制系统,并采用模糊自适应方法对轮毂电机进行转速控制。采用Matlab/Simulink软件对轮毂电机的转速控制进行仿真,对比分析了在加减速和负载转矩突变的情况下用作小型空轨车辆驱动轮的轮毂电机控制算法的性能。仿真结果表明,基于矢量控制策略,速度环采用模糊自适应PI算法与传统PI算法进行比较,小型空轨车辆转速控制的超调量减小3%,转速的稳定时间缩短。基于模糊自适应的轮毂电机控制算法满足小型空轨车辆的控制要求。
In this paper,traction control system scheme and drive motor control algorithm of micro sky train are analyzed.Firstly,control system of the micro sky train is built,and speed control of hub motor is carried out by fuzzy adaptive method.Matlab/Simulink is used to simulate the speed control of hub motor,and performance of the control algorithm of hub motor used as the driving wheel of micro sky train under circumstance of acceleration and deceleration and load torque mutation is compared and analyzed.Simulation results show that,based on vector control strategy,compared with traditional PI algorithm,speed loop adopting fuzzy adaptive PI algorithm has better dynamic and static performance,which makes speed overshoot of the micro sky train reduced 3%and stable time shorter.The hub motor control algorithm based on fuzzy adaptive algorithm meets the control requirements of the micro sky train.
