Abstract In view of the disadvantages of the current active heave compensation method of marine winches driven by AC (alternating current) variable frequency motors, such as large starting current, low efficiency and large energy consumption, an active heave compensation control method driven by switched reluctance motor (SRM) is proposed. Firstly, a mathematical model of SRM was established. Then, combined with the synchronous control requirements of the active heave compensation of the marine winch, a speed control method of SRM based on gradual steady state control signal-error control (GSSEC) was proposed, and its basic principle, specific design method and control parameter optimization method were analyzed. Finally, the effect of the speed control method of SRM was simulated and verified by experiment. The results showed that the speed control method of SRM based on GSSEC not only had high tracking accuracy for the time-varying given speed, but also had strong robustness to the load disturbance, which effectively improved the accuracy of the active heave compensation control of the marine winch. The research result is of great significance to promote the application of the active heave compensation control function of marine winches.

基于GSSEC的开关磁阻电机驱动的海洋绞车主动升沉补偿控制方法
针对目前采用交流变频电机驱动的海洋绞车主动升沉补偿方式存在起动电流大、效率低和能耗大等不足,提出采用开关磁阻电机(switched reluctance motor,SRM)驱动的主动升沉补偿控制方式。首先,建立了开关磁阻电机的数学模型;然后,结合海洋绞车主动升沉补偿的同步控制要求,提出了基于渐进稳态控制信号误差控制(gradual steady state control signal-error control, GSSEC)的开关磁阻电机调速控制方法,并分析了该控制方法的基本原理、具体设计方法及其控制参数的优化方法;最后,对开关磁阻电机调速控制方法的效果进行了仿真分析和试验验证。结果表明:基于GSSEC的开关磁阻电机调速控制方法不仅对时变给定转速有较高的跟踪精度,而且对负载扰动具有较强的鲁棒性,有效提高了海洋绞车主动升沉补偿控制的精度。研究结果对促进海洋绞车主动升沉补偿控制功能的应用具有重要意义。
