Abstract

|
|
The nuclear steam generator level control system is designed by robust control methods. The feedwater controller is designed by three methods of the H∞, the mixed weight sensitivity and the structured singular value. Then the controller located on the feedback loop of the level control system is designed. For the system performance, the controller of simple PID whose coefficients vary with the power is selected. The simulations show that the system has a good performance with proper stability margins.
