Problems solved by technology

However, in some occasions where it is necessary to change the target phase within a small range from the target speed and at the same time, when the phase control is completed, the speed returns to the target speed, it is difficult for the PI control strategy to complete the control of the speed and phase at the same time

Embodiment Construction

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] A speed control method that can control the phase of the motor. This method sets a desired motion trajectory curve of the speed and phase through the motor speed feedback signal, and makes the actual speed and phase of the motor control system move to the desired motion by designing a suitable motion control law. Trajectory curve, and further force the actual speed and phase of the motor control system to remain on the motion trajectory curve by designing a suitable con...

Abstract

The invention belongs to the technical field of helicopter model rotor tests, and discloses a rotating speed control method capable of controlling a motor phase, and the method comprises the steps: collecting an actual rotating speed signal of a motor; setting an expected rotating speed signal of the motor and an expected phase signal of the motor; determining a rotating speed error signal of themotor; according to the rotating speed error signal of the motor and the expected phase signal of the motor, setting a motion trail curve of the expected phase signal and the rotating speed error signal of the motor, and setting a keeping control law of the motion trail curve; setting a motion control law of the motion trail curve; according to the motion control law of the motion trail curve andthe keeping control law of the motion trail curve, enabling the expected phase signal and the rotating speed error signal of the motor to be changed according to the motion trail curve, and controlling the rotating speed and the phase of the motor at the same time.

Description

technical field [0001] The invention belongs to the technical field of helicopter model rotor tests, and in particular relates to a rotational speed control method capable of controlling motor phases. Background technique [0002] Since the permanent magnet synchronous motor is equipped with high-energy permanent magnets on the rotor without excitation, it has the advantages of small torque ripple, wide speed range, and simple structure, so it is widely used in control systems in aviation, aerospace, navigation and other fields. With the development of electronic technology, control theory and computer technology, the theory of high-performance control of permanent magnet synchronous motors has also been continuously developed. And the current motor control method can meet the performance requirements of the control system in most occasions. [0003] Using PI control mode to realize permanent magnet synchronous motor speed regulation is a relatively common strategy in curre...
