Smith-ADRC for Main Steam Pressure of CFBB

Article Preview

Abstract:

The main steam pressure control is one of the most important parts in Circulating Fluidized Bed Boiler (CFBB) control system. However, it is difficult to design controller because the combustion system of CFBB is an object that has many features: distributed parameters, nonlinear, time-varying and long time-delay. Therefore, in this paper, Smith-Active Disturbance Rejection Control (ADRC) is proposed and simulation results demonstrate the Smith-ADRC is effective in main steam pressure control.
