Application of Nonlinear Controller in Speed Control of Power Systems

F. Fatehi (USA)



In this paper we propose a nonlinear control technique to control generator speed in multimachine power system. The controller is applied to a steam turbine in a power system to control the generators speed at different operating points. The central idea of this approach is to algeberically transform a nonliear system dynamics into a fully or partly linear one, such that the linear control technique can be applied.
