This paper studies on high accuracy constant-speed system of BLDCM,in which dual-loop of speed and current control is used.Isolated functional blocks,such as Phase-locked Loop(PLL)block,and BLDCM block was modeled in Matlab7.0/Simulink circumstance.Then,speed controller based on PLL was established and used in constant-speed system of BLDCM.The validity of the model has been proved by simulation results,and it also verifies that PLL control can improve the stability of motor speed control.
