摘　　要：介绍了船模自航试验中电机直流调速控制系统的主要工作原理、控制方式及试验效果.该系统采用IG-BT大功率器件作为开关元件,采用PWM控制方式.设计了基于ATmega128和CPLD的直流调速控制系统,包括IGBT的驱动与保护电路、正交编码器接口电路.通过引入不完全微分PID控制,在实验中较好地实现了船模电机速度的控制要求.The working principle, controlling mode and testing effect of the DC regulating system for motor speed of ship model in self-propulsion test are depicted. The system chooses the high power IGBT element as the major switch of return-circuit： the PWM controlling mode is utilized. The system of DC regulating system is constructed with ATmega128 and CPLD, including a driving and protection circuit for IGBT and a QEP interface. Incomplete differential PID control is used so as to control the speed of ship model in experiment.
