Embodiment Construction

[0039] In this embodiment, a rotor dynamic balance control system based on fuzzy self-tuning single-neuron PID control includes: a rotor system, a balancing head, a vibration sensor, a fuzzy controller, a single-neuron PID controller, and a processor;

[0040] Such as figure 1 As shown, the control principle of this method is as follows:

[0041] The vibration sensor collects the vibration value y(k) of the rotor system at the kth cycle and transmits it to the processor, and the processor compares the received vibration signal y(k) with the set target value to obtain the kth The difference e(k) under the second cycle is used as an input value of the fuzzy controller; the processor performs differential calculation on the difference e(k), and the rate of change of the difference e(k) is obtained as another input of the fuzzy controller After the value is obtained, the fuzzy controller performs fuzzy processing to obtain the gain K(k) under the kth cycle; k≥1; wherein, the spec...

Abstract

The invention discloses a system based on fuzzy self-tuning single neure PID control and a method thereof. A fuzzy controller is used to calculate the gain K needed by a single neure PID controller, after the single neure PID controller obtains the gain K, a control step length is solved and obtained through the single neure PID controller, and finally the effective control of rotor unbalance is realized. The defects of low balance efficiency and low balance precision of a traditional PID control method can be overcome, thus the control efficiency is improved, and the effective control of a balance head is realized.

Description

technical field [0001] The invention relates to the field of dynamic balance control methods for rotating equipment, in particular to a rotor dynamic balance control system based on fuzzy self-tuning single neuron PID control and a method thereof. Background technique [0002] At present, rotating machinery is widely used in various aspects of industry. Due to the imbalance of the rotor, the rotating machinery will vibrate, which may seriously damage the machinery and cause unnecessary losses in engineering. In order to reduce these unnecessary losses and reduce the vibration of the rotor, the rotor must be dynamically balanced. [0003] At present, the traditional PID control method is widely used in the balance control of rotating machinery. However, the balance efficiency and balance accuracy of the traditional PID control method are not high, and the design of the traditional PID controller requires multiple experiments in advance to determine the control parameters. A...
