| Summary: | Due to the high efficiency and high performance of permanent magnet synchronous motors are used in various industries, such as aerospace. The main problem of achieving optimal performance control of PM synchronous motors is the heavy burden of control algorithms and large current pulsation. Due to the advantages of simple model predictive control algorithm and no need to set any control parameters, it is applied to the performance control of PM synchronous motors. The mid-point clamped three-level inverter is widely used because of its simple structure and versatility. However, the PM synchronous motor is susceptible to external load disturbances and internal parameter disturbances with large variations, and current harmonics and rotational arterial distance are difficult to control. In order to effectively solve the problem of disturbance disturbances, this paper proposes a functional disturbance observer (FDOB) based on the disturbance observer (DOB), which has the advantages of low order and handling more kinds of disturbances. In this paper, model predictive control and midpoint clamped three-level inverter are used. Compared with the traditional PI control method, the proposed functional disturbance observer plus model prediction control strategy can effectively reduce the disturbance perturbation of the motor, perform disturbance compensation, improve the motor speed response speed, improve the output current quality, enhance the system robustness and other advantages. |
