| Abstract: | A novel adaptive flux observer based on full-order observer is designed, in which motor current feedback is used to improve the robustness for the observer to the motor parameters. It reduces the errors of motor parameters and the influence on observation results caused by the inaccuracy and variety of the parameters. The online identifications of the motor speed and discretization of full-order observer are also introduced in this paper. A motor control system with TMS320F2407 as the controller is designed... |
