Abstract:
In this article, an interconnected adaptive observer-based backstepping control method is proposed to achieve sensorless current control without persistent excitation condition. Based on the stability theories of mathematics, an effective observer utilized to estimate the fluxes and external load is given. It has a good foundation for breaking the limitation caused by the coupling between the control process and the parameter estimation course. The characteristic of the uncoupling can make the control range for currents more wider. Due to the effective online tracking and the good adaptability of the designed observers, the control effect shows good robustness to the parameters. Finally, numerical simulations are provided to intuitively illustrate the effectiveness and the superiority of the theoretical results.
