[Abstract]:Permanent magnet synchronous motor (PMSM), as the core part of electromechanical energy conversion in modern transmission, has played an important role in industrial production due to its excellent performance. In recent years, with the rapid development of automation, the reliability and servo system performance of permanent magnet synchronous motor (PMSM) are required more and more. Compared with the electric excitation motor, the biggest problem of the permanent magnet synchronous motor is that the permanent magnet material has the risk of losing magnetic field, which also greatly limits the application scope of the permanent magnet synchronous motor. In addition, it is difficult to achieve the required dynamic performance of the current loop in the high performance servo system by using the coordinate transform based PID regulation. Therefore, aiming at improving the performance and reliability of the servo system, the fault tolerant control of permanent magnet synchronous motor (PMSM) is mainly studied on the basis of current loop control. The main contents of this paper are as follows: a fault tolerant control method based on the concept of effective flux linkage is proposed for permanent magnet synchronous motor (PMSM). Firstly, the effect of permanent magnet loss on current control is analyzed. Then, the observer based on sliding mode variable structure is designed in the static coordinate system with stator current as the state variable. According to the principle of sliding mode variable structure equivalent control, the calculation formula of dynamic monitoring effective flux is constructed. Finally, according to the current motor running condition and the observed value of the effective flux chain, the error elimination of the effective flux chain is realized by using the deadbeat control strategy, thus achieving the purpose of fault-tolerant control. This method can effectively control permanent magnet's magnetic loss or loss of magnetic field in time. A fault tolerant predictive control algorithm based on on-line flux detection is proposed to solve the problem that the load capacity of traction system is reduced due to the failure of permanent magnet synchronous motor (PMSM). Firstly, according to the predictive control model of PMSM, the influence of the failure of permanent magnet on current control and motor operation is analyzed in detail. Then, the observer based on sliding mode variable structure is designed, and the flux calculation formula of real time estimation permanent magnet is established by using sliding mode variable structure equivalent control principle. The state current observation value is calculated by the flux chain formula of permanent magnet. Finally, a fault-tolerant predictive control algorithm for PMSM is proposed. In this algorithm, the state current observations are input into the fault-tolerant predictive controller as feedbacks, so that the response current can accurately track the given current and thus achieve the purpose of fault-tolerant control.
