摘　　要：文章针对海上风电安装平台的升降系统在升/降过程中受到扰动后同步性能变差的问题,设计了基于幂次趋近律的滑模变结构控制方法,用来提高升降系统的同步性能和抗干扰能力。文章采用滑模控制器设计转速环控制器,应用偏差耦合同步控制策略,对同步误差控制器作出改进。利用Simulink建立了4台异步电机的同步控制模型,分别验证了单电机的滑模控制和多电机的滑模同步控制的控制效果,并根据仿真图像分析,得出了以下结论,即对于单电机控制,滑模控制的效果较PI控制器具有更高的鲁棒性;对于多电机同步控制,滑模同步误差控制器相较传统偏差耦合控制策略,同步精度高,且鲁棒性强。This paper designs a sliding mode variable structure control method based on the power reaching law to improve the synchronization performance and anti-interference ability of the lifting system of the offshore wind power installation platform.The study adopts the sliding mode controller to design the speed loop controller and ap-plies the deviation coupling synchronous control strategy to improve the synchronous error controller.This paper es-tablishes the synchronous control model of four asynchronous motors via Simulink to verify the control effect of sliding mode control of a single motor and sliding mode synchronous control of multiple motors,respectively.The results of simulation image analysis demonstrate that the effect of sliding mode control is more robust than that of PI controller for single-motor control;for multi-motor synchronous control,the sliding mode synchronous error controller has higher synchronization accuracy and stronger robustness than the traditional deviation coupling control strategy.
