| Abstract: | From the anlysis of MRAS and SMO,a control method based on PMSM which is a combination of MRAS and SMO was proposed.The estimation of stator current is realized by SMO method which is composed of the adjustable model of MRAS method and realized the estimation of the rotor speed as well as the three close-loop feedback control of the whole system.How to build a speed sensorless control system of PMSM was illustrated based on the combination of MRAS and SMO and tested it.The test turned out that this control system have a good low speed adjustment and dynamic performance and robustness. |
