Description

Technical Field

[0001] The present invention relates to the technical field of direct-drive motor startup control parameter optimization, and in particular to a direct-drive motor startup control parameter optimization method and system. Background Art

[0002] The characteristic of a direct-drive motor is that the load is directly connected to the motor rotor, omitting the transmission device (such as gears or belts) in a traditional motor, so that the rotational motion is directly transmitted to the load. Motors of this design are usually called "direct-drive motors" or "gearless motors". Compared with traditional motors, direct-drive motors have some advantages, such as higher efficiency, lower mechanical losses, smaller size and higher dynamic response capabilities. However, the control system of the direct-drive motor is crucial to realizing these advantages.

[0003] Generally, the control system of a direct-drive motor usually adopts a fixed-parameter control strategy, which is unable to adjust the control parameters in real time to adapt to different working conditions and load conditions. It lacks robustness to external disturbances and changes in system parameters, resulting in performance fluctuations of the system under different working conditions. During the motor startup process, detailed parameter optimization may not be performed, resulting in low startup efficiency, slow response speed or startup shock. It also lacks a complete current monitoring and protection mechanism, is susceptible to overload or damage caused by external factors, and cannot be adjusted in real time according to changes in the motor's working conditions. Therefore, it may perform poorly in a variety of working environments. Therefore, the control system of a traditional direct-drive motor performs poorly in achieving optimal efficiency.
