Abstract:
Induction motor is a complex nonlinear structure where strong coupling exists between rotor flux and produced electromagnetic torque.So, different
decoupling techniques are applied to decouple the system which make the
control design easy.Moreover, the proposed model of the motor has nonlinearities and parametric uncertainties which make control more difficult.In
the thesis Multi-scalar variable model is used to decouple the complex motor
structure,which transform the system in two subsystems namely mechanical and electromagnetic.As the presented system is nonlinear so a nonlinear
control scheme is better choice to control such system.In this research work
Backstepping controller of the system is proposed which gives better performance than conventional techniques. All the simulations are done in the
MATLAB/SIMULINK. For mathematical analysis Laypunov theory is used
to prove the stability of the proposed control.Comparison of proposed controller and conventional control techniques from literature is also done to
show the robustness of controller.
