Abstract：Aiming at the problem that the traditional PID can not obtain good control effect in the complex pressurizer control system of nuclear power station, a fractional order auto disturbance rejection controller ( FOADRC ) was proposed. Both fractional order controller and auto disturbance rejection controller ( ADRC) were combined in the present controller, so that the controller could not only have the rapidity and high precision features of fractional order controller, but also have the strong robustness and disturbance rejection performance of ADRC. Therefore, the problem of difficult parameter adjustment in the nonlinear state error feedback control law in ADRC technology gets solved. The established Simulink simulation model for the pressure control of pressurizer reveals that compared with the traditional PID control and ADRC control, the FOADRC has better performance indexes.
