Özet

Sliding mode control is an effective methodology for controlling systems with variable structures, providing a systematic approach to the problem of maintaining stability and consistent performance in the presence of modeling imprecision, uncertainties, and disturbances. The observation problem of the uncertain and nonlinear nu-clear systems is investigated by using sliding mode observers (SMOs). Three different applications with uncertainties are under consideration: point reactor kinetics equations, nonlinear xenon dynamics, and a U-tube steam generator system. Numerical results are presented to illustrate the effectiveness of the SMO.
