Robust Nonlinear Control of Linear Induction Motor taking into account the Primary End Effects

This paper presents a robust nonlinear controller for speed and flux control of primary type linear induction motor (LIM) drive. The proposed controller is designed based on combination of input-output feedback linearization and sliding-mode (SM) control taking into account the LIM end effects. The stability of proposed composite controller is proved by Lyapunov theory. The effectiveness and validity of the nonlinear controller system is supported by computer simulation. Simulation results obtained, confirm that the drive system controller is robust an stable against the parameters variations and external unknown load force
