The Design and Implementation of Brushless DC Motor Control System
The paper designs a brushless direct current motor (BLDCM) control system, mainly including design of former stage driver circuit, H bridge drive circuit, sensor commutation control, Forward / reverse control. In order to increase the reliability of the system, improve the performance of motor running, one has a good choice of parameters about power amplifying circuit device. What is more, one adopts PID algorithm in the system. Experiments show that the operating speed is with wide speed range from 150 r/min to 4000r/min. Through the adjusting of PID parameters, the error of speed can be stabilized within 5r/min, the system exhibits very good performance. Both hardware implementation and software control algorithms are reliable. The system has a wide range of practical value.
