摘　　要：阐述了一种利用PI控制来直接消除估算转速和实际转速误差的自适应估算转速法。在高速时,其动态和静态性能较好,估算转速能与实际转速基本重合;在低速时,整个系统性能稳定,估算转速也能实时跟随到实际转速。Based on PI control, a novel rotor speed estimation algorithm using model reference adaptive system （MRAS）is proposed to eliminate the error between estimated speed and real speed. The .dynamic and static performance of the system are quite well and the estimated speed could keep the same value as the real speed when the motor running in the high speed state. Likewise, even if the motor running in the very low speed state, the system could still run stably, and the value of estimated speed could also follow with the real speed.
