摘　　要：分析了80C196KC单片机的功能特点并将其应用于直流电机调速系统中。从数字式直流调速系统的数学模型出发,选定电流、转速双闭环的数字PI控制方案,可实现直流电机的高精度调速。系统具有速度预置、速度实时显示等功能。The paper researches double loop DC motor control system based on 80C196KC. The 80C196KC has been applied successfully to the system after its character was analyzed clearly. The PI control strategy of double loop which composed of current and speed is selected by studying the math model of the system, and then it can be attain a high precision and performance of the speed control, which also has a speed preset and display. The technique has referenced value to some small DC motor control systems.
