摘　　要：针对电网相控变流器供电的直流调速系统存在的诸多缺点 ,给出了由电压负反馈和电流正反馈补偿代替测速机且采用绝缘栅极场效应管MOSFET实现脉冲宽度调制的无测速机调速系统A notachogenertor speed regulating system is presented for the DC speed regulating system of electrified wire netting phase control inverter supplying power in which voltage negative feedback and current positive feedback take the place of tachogenertor as speed feedback and DC PWM technology is used with the MOSFET.Using DC PWM technology in DC motor driving speed control system can greatly quicken the systems speed reponse and can improve the system function.The experiment result proves that the system keeps fine quality of control.

关 键 词：无测速机 脉冲宽度调制 绝缘栅极场效应管 调速系统 直流电机
