Problems solved by technology

[0004] However, the traditional brain emotion controller only considers the thalamus, sensory cortex, amygdala and orbitofrontal cortex in the limbic system, only realizes a small part of the complex functions of the limbic system, and does not really realize the working mechanism of the limbic system, namely The judging mechanism of the limbic system cannot be realized, and the emotional response effect of the amygdala cannot be judged
The traditional brain emotion controller is used as a speed controller. Although it can improve the tracking effect on the speed of the permanent magnet synchronous motor, the improvement is limited. However, the traditional brain emotion controller will continue to repeatedly adjust during speed tracking, and the efficiency is low

Abstract

The invention relates to a permanent magnet synchronous motor control method of a brain emotion controller based on experience information, which comprises the following steps of: 1, sampling the rotating speed and three-phase current of a permanent magnet synchronous motor in real time, calculating a speed error and converting the speed error into a stimulation signal and a reward signal; 2, designing a brain emotion controller based on experience information, inputting the stimulation signal and the reward signal into the brain emotion controller based on the experience information, and outputting a torque reference value by the brain emotion controller based on the experience information, wherein a dorsolateral prefrontal cortex receives the stimulation signal, the reward signal and difference signal generated by the output of the amygdaloid body to judge the tracking effect of the amygdaloid body on the reward signals, and the weight updating speed of each stimulation signal in the amygdaloid body is adjusted according to the tracking effect; and 3, taking a brain emotion controller based on experience information as a speed controller. According to the method, the speed of the permanent magnet synchronous motor can be judged, and the speed tracking performance of the speed controller is improved.

Description

technical field [0001] The invention belongs to the technical field of permanent magnet synchronous motors, in particular to a permanent magnet synchronous motor control method of a brain emotion controller based on experience information. Background technique [0002] Permanent magnet synchronous motors have the advantages of small size, simple structure, high power factor, small moment of inertia and fast response, and are widely used in various occasions such as aerospace, petroleum industry and industrial robots. The unmeasurable nonlinear quantity produced by the complex driving mechanism of the permanent magnet synchronous motor will affect the speed of the motor. Quickly restore the speed level in the disturbance. [0003] The brain emotion control algorithm is proposed based on the signal transmission logic between several major organizations in the limbic system of mammals. Compared with other control algorithms, it has the advantages of fast speed, self-adaptation...
