摘要

This paper presents a speed-sensorless separately excited dc motor drive which uses the simple observer [6] to estimate the rotor speed & also involves the design and simulation of a microcontroller-based sensorless speed control of permanent magnet DC motor. The basic feedback circuit in closed loop speed control of motor is replaced by an observer which estimates the speed(ω) by using motor parameters(R, J, k,L) & line variables(V,I, dIa /dt). The speed control is achieved by using armature voltage control, which is controlled by changing duty ratio of chopper.
