摘　　要：介绍了以一种超低功耗16位混合信号单片机MSP430F449作为核心控制芯片,光电编码器检测直流电机转速构成速度反馈,MSP430F449的定时器生成PWM,应用功率驱动芯片L298N构成驱动电路,采用PID控制算法,实现了直流电动机转速的闭环控制。给出了硬件原理图和相应的软件设计流程。This paper introduces MSP430F449 that is a kind of ultralow-power consumption 16-bit mixed signal microcontroller. The feedback speed is formed by photoelectric encoder. Regulating speed is achieved by PWM. L298N chip is adapted to drive DC electromotor. PID algorithm implements closed- loop control function. The circuit of hardware and corresponding software of the design are also given.
