Abstract :
For the power control system of thermal power unit, a two degree of freedom control structure is designed and the parameters of the controller are determined. In the process of design, the problem that the mechanical power of turbine can not be measured is solved by changing the structure and other methods. Compared with other two kinds of control system, the classic feedforward-feedback control and the inner model control, the simulation results show that the two degree of freedom control system can meet the requirements of system well and the performance is better than the other two.
