英文摘要： Several constraints, which the mechanical position sensor imposes on the motor operation,can be dealt with by using sensorless operation of Permanent Magnet Synchronous Motor(PMSM),which is the current research focus. However,there exist several problems in the stable operation of the PMSM sensorless, which has restricted the scope of the applications of the PMSM sensorless.Therefore, this project is concerned with the integration bewteen the structure optimization of the PMSM and sensorless,and makes of use new control approaches to obtain motor operation with high performance.Specifically,the main content in this project is listed in the following.Firstly,due to easily controlling and dectecting the rotor position,the method of circuit-field will be used to design and optimize the structure of PMSM.Secondly,the detection theory of the rotor position and smooth switching with the velocity change from zero to maximum will be studied, which can result in severl new technologies to be proposed.Thirdly,due to the complexity of coupling bwteen mechanics and electrics for the sensorless PMSM,several advanced control approaches will be employed to cope with the internal parameter disturbation and external disturbance such that sensorless PMSM can stably and effectively operate.Finally,the experimental prototype of the
