The Steam Generator Water Level System Based on Nonlinear First Order ADRC Control

Abstract:

The Steam Generator with the characteristics nonlinear, time varying, and non-minimum phase whose water level will fluctuate significantly when it encounters inner disturbance or outside interference. For the above problem, the ADRC of steam generator will be designed in this article. Based on the dynamic characteristics of steam generator, equivalent the steam generator model to be the generalized first order system and establish control system based on nonlinear first order ADRC. The simulation results show that the proposed control strategy can achieve better control performance.
