摘要
设计了一种兼有PWM(Pulse Width Modulation,脉冲宽度调制)和模拟量控制的直流电动机闭环控制系统。系统以DSP芯片TMS320F2812为核心控制器件,采用Solid Motion SAEG系列36SYK71直流伺服电机,运用增量式PID(Proportional-Integral-Derivative,比例-积分-微分)控制算法,利用串口和PC机通信,通过DSP发送PWM波及控制信号给驱动电路来控制电机转动,实现了利用上位机对电机进行闭环控制和运动状态的实时显示。对系统进行了实验测试,结果表明引入增量式PID技术后其控制精度有了提高。
This paper designed a DC motor closed-loop control system with function of PWM （pulse width modulation） and analog control.The system selected the DSP TMS320F2812 as the core chipset to control the motion of the solid motion SAEG series 36SYK71 DC motor in real-time by using the incremental PID （proportional-integral-derivative） algorithm.The serial port was used as a communication port to send the instructions of PWM and control signals to DSP for realizing a closed-loop control of the DC motor.Experimental results show that the proposed system can improve the accuracy of control by introducing the incremental PID technology.
