| 英文摘要 |
| To minimize the torque ripple caused by the nonlinear characteristics, this paper regards switched reluctance
motor as the spatial repetitive motion object, and then designs a current and torque compensation mechanism based on
active disturbance rejection based iterative learning control (ADR-ILC), which is a novel data-driven control strategy. The
torque sharing function is used to distribute the given torque to each phase, and a non-linear torque compensator based on
ADR-ILC is added to the ”torque-current” conversion module to compensate for nonlinear error, which can accurately complete the ”torque-current” conversion without accurately knowing the motor model. Similarly,current tracking is achieved
accurately by applying ADR-ILC controller. Simulation shows that the control strategy based on ADR-ILC can suppress
torque ripple significantly and quickly, which is expected to play a role in the practical application. |
