Hamilton system modeling and passive control for induction motor of electric vehicles by considering iron losses
计及铁损时电动汽车用感应电机的Hamilton建模及无源控制

In view of the nonlinear characteristics of the electric vehicle drive system, we apply the port-controlled Hamilton system theory and the passivity-based control theory to investigate the modeling and control of induction motor with iron losses in electric vehicles. The total energy of the system is considered the Hamilton function, based on which the port-controlled Hamilton dissipative model of the induction motor with iron losses is derived in a synchronously rotating frame; and then, the passive controller of the closed-loop electric vehicle drive system is designed by using the method of interconnection and damping assignment. The stability of the closed-loop system is analyzed as well. Because the Hamilton function of the closed-loop system is used as the Lyapunov storage function in the global stability analysis of the system, both the design and implementation of the controller becomes simpler and easier. The simulation validates the efficacy of the proposed control scheme.
