针对传统的积分环节跟踪交流输入信号可能产生幅度和相位误差的问题,基于PR调节器提出一种改进的异步电机转子磁链观测方法,这种方法可以降低转子电动势积分的静态误差,具有良好的磁链和转速观测精度,改善了磁链的畸变和运行特性.系统仿真与实验结果均验证了该方法的有效性.
Concerning that the problem of traditional intergration regulator was likely to produce amplitude andphase errors for AC input signal,an improved induction motor rotor flux observation method based on P+ResonantRegulator was proposed. This method can decrease steady?state errors of the integration of rotor EMF,has preferablyobserve precision of rotor flux and speed of motor,reduce the degree of flux aberration and run characteristic.Experimental and simulation results are presented to fully support the claims.
