摘要：For speed tracking control of Interior Permanent Magnet Synchronous Motor (IPMSM) used in the electric vehicle, a new adaptive backstepping control theory based on Maximum Torque Per Ampere (MTPA) control rule is proposed in this paper. By designing virtual control input and choosing appropriate Lyapunov functions, the speed controller and parameter estimation laws are derived. The overall control system is globally asymptotically stable. Simulation results show the proposed controller has good speed tracking performance, and ensures strong robustness against the parameter uncertainties and unknown bounded load torque disturbance, which is useful to improve drivability and comfort of the electric vehicle. © 2014 ISSN 1881-803X.
