摘　　要：在他励直流电机的数学模型的基础上,得到了单反馈闭环控制的直流调速系统的结构。以MSP430为核心设计了直流调速系统的电机驱动和光电码盘反馈控制电路,研究了增量式PID控制算法和MSP430程序,实现了低成本的直流电机转速无静差控制方法。Based on the mathematic model of separately excited DC motor,the control structure of the single- feedback-closed-loop controlled DC velocity modulation system was obtained. With MSP430 as controlling core, motor driven circuit and opto-electrical coder feedback-based controlling circuit of DC velocity modulation system were designed and the incremental PID algorithm and the velocity controlling program were investigated. Using the new design, a kind of DC motor velocity controlling method with feature of low cost and no static error was realized.
