A Parameter Setting Method of the Speed ​​Loop Active Disturbance Rejection Controller of Permanent Magnet Synchronous Motor

Abstract

The invention discloses a parameter tuning method of the speed loop self-disturbance rejection controller of a permanent magnet synchronous motor, establishes a double closed-loop control structure of speed and current, and initializes the gray wolf population strategy according to the Tent mapping reverse learning, and adopts the non-linear method as the number of iterations increases Change the convergence factor, and introduce the levy flight strategy in the update link of the wolf pack position in the algorithm for mutation operation, and finally obtain the adjusted parameters. The present invention improves the gray wolf optimization algorithm population from the initialization, initializes the gray wolf population according to the tent mapping reverse learning strategy, designs a convergence factor that changes non-linearly with the increase of the number of iterations, and introduces the levy flight strategy in the wolf group position update link. An improved gray wolf optimization algorithm is proposed, which can increase the diversity of the initial population of the algorithm, better adaptability and adjustment to complex searches, avoid falling into local optimum, improve the convergence speed of the algorithm and the global optimization ability, and the effect It is better than other improved gray wolf optimization algorithms.

Description

technical field [0001] The invention relates to the technical field of synchronous motors, in particular to a method for parameter setting of a permanent magnet synchronous motor speed loop active disturbance rejection controller based on an IGWO algorithm. Background technique [0002] Compared with ordinary motors, permanent magnet synchronous motors have the characteristics of small size, simple structure, high torque-to-inertia ratio, and high reliability. Relying on their own performance advantages, they have been widely used in the field of industrial automation. However, the permanent magnet synchronous motor is a multivariable and strongly coupled nonlinear system, and there are also factors such as parameter changes and load disturbances. The conventional PID control is difficult to meet the realistic control requirements, which will lead to the speed control performance of the permanent magnet synchronous motor. decrease, affecting the control effect of the system....
