摘要
设计了一种基于LM3S811的多路电机控制系统。该系统以LM3S811微控制器作为系统核心,电机驱动芯片MC33887通过微控制器产生的PWM控制信号来控制各个电机的运转,信号采集模块通过多路开关的选择可以实现对多路电机的监测,从而实现电机的闭环控制。软件中运用中断机制,实现对指令的初步解析,系统可以同步控制多路电机按照一定轨迹运动,同时可以调节电机运动的加减速参数。试验结果表明,该系统具有良好的稳定性。
In this paper,a multi-channel motor control system based on LM3S811 is designed. The system uses LM3S811 microcontroller as the core of the system,motor drive chip MC33887 through the PWM control signal generated by a microcontroller to control the motor running,the signal acquisition module through a multiplexer switch selection can achieve monitoring of multi-channel motor,so as to realize the closed-loop control of motor. In the software,interrupt mechanism is applied to realize the preliminary analysis of the instructions. The system can synchronously control the movement of multiple motors according to certain trajectories, and at the same time, can adjust the acceleration and deceleration parameters of motor motion. The test results show that the system has good stability.
