Abstract :
Boiler steam temperature in thermal power plant is very complex and hard to control, many control strategies have been applied to it. Linear Active Disturbance Rejection Controller (LADRC) is adopted to the control of boiler steam temperature in this paper. The nonlinear model of boiler steam temperature is set up firstly, then the principle of the LADRC is briefly introduced and the LADRC based boiler steam temperature closed loop control system is designed and the closed loop system is studied with simulation. Compared with the traditional PID, more robust and better disturbance rejection properties are obtained.
