The Model. The nonlinear drum boiler model has three control inputs: feedwater flow rate, heat input and position of a valve at the steam outlet. The feedwater needs to be controlled so that the water level inside the drum is kept at its set point. A PI control loop is added for this purpose. Complete drum boiler model, including evaporator and Get Price
