Abstract: A new kind of toroidal motor with hybrid excitation was presented. The mathematical model of the motor was built based on the structural characteristics and driving principle. Step response characteristics of the motor were analyzed. Aiming at the problem of rapidity and stability for the response, a PID controller was designed based on ITAE criterion, disturbance rejection of the control system was analyzed. The simulation research on the response characteristics of the control system demonstrates that the control strategy is superior to the conventional PID in speed tracking power, it has strong robustness to external disturbance and provides the motor with a theoretical basis in the design of control system.
Key words: hybrid excitation；toroidal motor；ITAE criterion；robustness
