Abstract：A feedback linearization control strategy of induction machines which features not introducing zero dynamics is proposed based on the input-output feedback linearization theory after selecting the novel affine nonlinearity model of induction machines. As a result, the complicated analysis of the stability of the zero dynamics is avoided．In order to make the system be equivalent to the two decoupled independent linear systems, the decoupling matrix is derived, therefore, the design of the controllers for induction motor speed control systems is simplified. The simulation results and the experimental results show that the decoupling control of induction machines, which are nonlinear controlled objects, is effectively realized via the proposed feedback linearization control strategy of induction machines without introducing zero dynamics, the static and dynamic performance, and the robustness of the system are excellent.
