Abstract:
This paper provides an adaptive robust position/thrust tracking control for the linear induction motor (LIM) with unknown end-effect. In the position control, a backstepping method is developed to overcome parametric uncertainties and uncertain nonlinearities. In the thrust control, electromagnetic thrust and flux is calculated in order to overcome the fluctuation of the thrust and velocity caused by end-effect. For the influence of parametric uncertainties on LIM, a discontinuous projection-type method is used to estimate the system parameters. Under the assumption that the disturbance is bounded, the boundary value is used to design the control law and to make the system energy within a certain range. Through the dual control of position and thrust, it can improve the trajectory tracking performance and stability of LIM. Simulation results and comparative experimental results prove the improved tracking accuracy and validate the effectiveness of the proposed method.
