A decoupling control method based on a new type of artificial neural network (ANN) generalized inverse is proposed for induction motor which is a multivariable and high coupling system. The existence of the new type of generalized inverse was proved. The composition of the generalized inverse and the inductor motor decoupled the rotor flux and rotor speed into two independent pseudo-linear subsystems ,the poles of which can be assigned anytime by regulating the feedback parameters which were beneficial to the design of controller. Simulation results show that the whole control system has strong robustness to variation of motor parameters and load torque disturbance by assigning poles and choosing parameter of the controller appropriately.
