摘　　要：在中小型直流调速系统中 ,一般都取消了测速发电机 ,而以电枢电压作为电机转速信号。提出了直接测取电枢电流i且构成u(i)环节来取代测速发电机的方法 ,并提供了经实用运行的简化原理图。In general,tachometer generators are eliminated in the small and medium power DC rotating speed governing systems,and armature voltage is used as motor speed signal.In this paper,the direct measurement of armature current i is proposed,and the measured current i is used to form u ( i ) function.This approach can replace the function of tachometer generator.In addition,a simplified diagram that has been used in the real application is also provided.
