Embodiment Construction

[0039] A parameter self-adaptive fractional order active disturbance rejection automatic power generation control method proposed by the present invention is described in detail in conjunction with the accompanying drawings as follows:

[0040] figure 1 It is a structural diagram of the parameter adaptive fractional order active disturbance rejection controller of the method of the present invention. The fractional-order active disturbance rejection controller is composed of fractional-order extended state observer and fractional-order state error feedback. The fractional-order ADRC controller combines the advantages of the fractional-order control idea and the ADRR algorithm to obtain higher performance and stronger anti-disturbance ability. The design of fractional order controller is an improvement of the robust performance of active disturbance rejection controller. Taking the fractional-order ADRC controller with a three-order structure as an example, the fractional-ord...

Abstract

The invention provides a parameter adaptive fractional order active disturbance rejection automatic generation control method. The method combines a fractional order control idea and an active disturbance rejection algorithm with a component number order active disturbance rejection algorithm, and then applies a parameter adaptive strategy to the fractional order active disturbance rejection algorithm. The method of the invention improves the control performance of the fractional order through a computer to improve the control performance of the automatic generation control system. The methodcan eliminate the fussy process of manually adjusting controller parameters. The method automatically adjusts the parameters of the system by using a parameter adaptive algorithm, and the adjusted fractional-order auto-disturbance rejection model can obtain high control performance without good manual adjustment parameters, and the anti-interference ability is good.

Description

technical field [0001] The invention belongs to the field of automatic power generation control of electric power systems, and relates to an automatic power generation control method based on the combination of parameter self-adaptive strategy, fractional order control thought and active disturbance rejection algorithm, which is applicable to the problem of automatic power generation control of electric power systems. Background technique [0002] With the continuous development of science and technology and the continuous improvement of control level, the traditional proportional-integral-derivative controller is still widely used in the field of automatic control technology. However, the parameters of the controlled object in the actual control system change, and change with the internal and external environmental disturbances of the controller, which causes a certain error between the expected value and the actual value. In recent years, many researchers have proposed man...
