转镜高速相机的电机调速系统设计

The Motor Speed Control for High-speed Rotating-mirror Camera

转镜高速相机的转镜驱动电机通常采用特种高速直流调速电机 ,对启动控制要求较高。而转镜高速相机不但要求其转镜驱动电机有较高的调速精度 ,还对整个转速—时间曲线提出了要求。这里介绍的计算机控制电机调速系统采用了专家控制型控制策略 ,使用了驱动简单、热稳定性好的绝缘门双极型晶体管 (IGBT)作功率放大元件 ,满足了转镜高速相机的需求。

The motor driving the rotating-mirror of high-speed camera is a special kind of DC high-speed motor,which need a delicate start control.And the rotating mirror requires not only accurate speed adjustment,but also the control of the speed-time curve.The computer control introduced utilized the expert control stratagem,and adopted the isolated gate bipolar transistor (IGBT) as its power amplifier.This system satisfied the requirement of the rotating mirror.
