RISE-Backsteppping feedback control for induction machine in electric vehicle applications

This paper deals with the synthesis of a speed and flux control strategy for a class of motor control characterized by its highly nonlinear and multivariable dynamic, induction motor drive. A new continuous control law is proposed using a combination of the backstepping design with the Robust Integral Sign of the Error (RISE) technique in the presence of additive load disturbances. The modified backstepping design is asymptotically stable in the context of Lyapunov theory under the assumptions that the disturbances are C² class fuctions with bounded time derivatives. Moreover, the boundedness of the closed-loop signals is ensured. Simulation results are provided to illustarte the effetiveness of the proposed approach.
