Abstract

The invention provides a method for controlling the angular velocity of a permanent magnet synchronous motor using self-adaptation and direct-feed compensation, and relates to the technical field of motor design and control. The method includes the following steps: performing Clarke transformation on the stator current to obtain the stator current in the two-phase stationary coordinate system and Parker transform the stator current in the two-phase stationary coordinate system and the rotor position to obtain the stator current in the two-phase rotating coordinate system; design the second one according to the first current error signal and the first nonlinear adaptive control law Stator voltage; design the expected value of the second stator current according to the angular velocity error signal; design the first stator voltage according to the second current error signal and the preset second nonlinear adaptive control law; use the third stator voltage and the fourth stator voltage The voltage is output to the permanent magnet synchronous motor through the three-phase inverter to complete the control of the angular velocity of the permanent magnet synchronous motor. The invention improves the accuracy of controlling the angular velocity of the permanent magnet synchronous motor.

Description

Technical field [0001] The present invention relates to the field of motor design and control technology, and in particular, a method of adapting an angular magnet synchronous motor angular velocity control using adaptive and direct feed. Background technique [0002] Permanent magnet synchronous motors are increasingly widely used in servo systems that are relatively high in control performance due to its simple structure, reliable, wide-speed range, and efficiency. [0003] With the development of microprocessors, the intelligent control of permanent magnet synchronous motors is achieved by complex algorithms, and it has also caused more and more research and development personnel in recent years. Due to the change of the permanent magnet synchronous motor, the rotational inertia also changes in a large change; and when used in different environmental conditions, the friction coefficients also change. [0004] Therefore, in the conventional relying on exact model parameters, it...
