摘要：
Flux vector estimation accuracy is affected by the rotor parameters in rotor flux-oriented control. The algorithm has the disadvantage of sensitivity to rotor parameters. Aimed at these problems, a control strategy of induction motors with stator flux orientation is presented. According to the dynamic model of induction motors, stator flux and rotor speed are controlled respectively. The main improvement is that stator flux and rotor speed are decoupled dynamically. Additional, a new integration is proposed in this paper. A modified integrator using the proposed algorithm is developed to solve the problems associated with pure integrator. Finally, the performance of the control scheme is verified on the dSPACE platform. According to the result of the experiment, decoupling control of the scheme is achieved. The dynamic and static results are satisfactory.
