Abstract: In this paper, a type 1 Fuzzy controller is composed for solving change in load frequency problem of single area thermal power system. The performances of type 1 fuzzy controller have been demonstrated for comparing the performances of other published paper PID controller such as Ziegler Nichols method. A single area non-reheat thermal power plant with Fuzzy controller is simulated in MATLAB/SIMULINK platform due to a step change in load demand. The proposed fuzzy controller gives better dynamic responses of the power system in terms of Settling time, Peak Overshoot and Peak Undershoot.

Abstract: Most industrial processes have time-varying parameters, the Induction Motor IM is a typical example, in fact the rotor resistance (Rr) can vary and reach 100% of its nominal value during operation because of the heating of the rotor, the effect of the variation of the stator resistance (Rs) is very influential at low speed for our case because it can go up to 50% of its initial value, it is proposed in this work to developed a method that involves the observation of the speed and the simultaneous estimation of the principal parameters varying in time, and in particular the estimation of the stator resistance Rs and rotor Rr of the induction motor using sliding-mode observer when only the stator currents and voltages are accessible by measurement. After the theoretical study we will validate the method proposed by the simulation results where we will show the fairly fast convergence of this method as well as its robustness.
