| Abstract: | Based on basic electromagnetism theory, a radial force model of a bear ingless switched reluctance motor is given. Reversibility of the model is proved and a neural network inverse approach is developed for the nonlinear, str ongly coupled model. A nonlinear controller based on neural network inverse syst em is designed so that the nonlinear, strongly coupled system is decoupled into two linear subsystems. Furthermore, linear control system techniques are applied to these decoupled linear subsystems to synthesize desired response. To verify the effectiveness of the control scheme, some simulations were carried out and t he results are satisfactory. |
