Study on the CFBB Main Steam Pressure Control System Based on ADRC Technology

Abstract:

The combustion process of CFBB is a system with time-varying, nonlinear, large inertia and time delay. Therefore the control effects of traditional PID control system in the CFBB plant are not satisfactory , especially the overshoot of the main steam pressure control system is very big, and the adjustment time is too long. To improve the performance of the main steam pressure control system, ADRC technology was used . The disturbed signal was added in the different operating conditions, the testing results indicated that the ADRC main steam pressure control system had more excellent performance than the convention PID method.
