Abstract

Abstract

The once-through steam generator (OTSG) has small water capacity and heat storage capacity, and its mathematical model is uncertain and nonlinear. When there are disturbances and load changes, the steam pressure fluctuates greatly, which adversely affects the system equipment. The conventional proportional-integral-derivative (PID) control has some disadvantages, such as overshoot, poor anti-disturbance performance, etc., which is difficult to meet the system performance requirements. To solve the above problems, the active disturbance rejection control (ADRC) is used to control the steam pressure of OTSG. However, because there are many parameters to be tuned in ADRC, the shuffled frog-leaping algorithm (SFLA) is improved and optimized in this paper, which is used to optimize the parameters of ADRC, and a simulation model is established for simulation test. The results show that the ADRC with improved SFLA for parameter self-tuning can realize fast tracking control of OTSG without overshoot, reduce the control error of steam pressure, and has good anti-disturbance ability.
