为实现卡线器安装装置的轻量化设计以及行走速度稳定控制的需求,提出了一种压线轮步进电机加速与减速控制的方法。基于系统受力状态分析,计算不同驱动力下的负载特性和步进电机转矩频率特性,使用迭代法求解电机的最优加速速率。在微处理器电路上编制程序,实现了驱动电机的稳定起动、行走及制动,实物试验验证改算法的有效性。

A method for accelerating and decelerating the tension wheel stepper motor was proposed to meet the requirements of lightweight design and stable control of walking speed of the grip clamp installation device.Based on the analysis of the system's force state,the load characteristics was calculated and torque frequency characteristics of the stepper motor was determined under different driving forces.The iterative method was used to solve for the optimal acceleration rate of the motor.The program was applied on the microprocessor circuit to achieve stable starting,walking,and braking of the drive motor,and the effectiveness of the algorithm was verified through physical testing.
