Abstract :
The loss-free resistor (LFR) is applied to a DC motor speed control system. A instantaneous value compensation algorithm based on LFR is proposed. The variations of the motor speed is realized by controlling the output of the LFR, and the energy loss in the system is reduced compared with using a conventional power amplifier. Dynamic characteristics of the system are also improved. The overshooting of the system is eliminated and the response time of the system is reduced. The control method is suitable for the systems that are demanded to have no overshoot but to have quite quick response such as the robot speed-position control system and some mechanical process control system
