英文摘要：

For the high order, nonlinear and strong coupling characteristics of induction motors, Hamiltonian control strategy was proposed based on the calculated equilibrium points. Hamiltonian mathematical model of induction motor was constructed by reselecting the state variables based on port-controlled dissipation Hamiltonian theory, and then Hamiltonian controller for induction motor was designed with the method of calculated equilibrium points. Damping pa- rameters were analyzed through theoretical analysis and determined by considering the overall performance of control system. For load disturbance problems, the load torque observer was desigened to improve the speed robustness. Exper- imental results showed that the new proposed Hamiltonian controller for induction motor had a good overall performance with speed dynamic response, steady accuracy and load anti-disturbance, thus Hamiltonian theory provides a new way of high-performance control for induction motor.
