| Abstract: | Using multi-index nonlinear integrated control theory, the high pressure valve, and the intermediate pressure valve and the excitation control are considered in a unified nonlinear frame, the dynamic process of the intermediate superheater is also taken into account. A multi-index nonlinear integrated controller for high power turbogenerator has been designed. The simulation results show that this controller can give consideration to the response characteristics of many state variables in the controlled system at the same time and can coordinate the dynamic and static characteristics of the system, and give the generator a satisfied output characteristic. |
