现代风帆助航技术的研究与应用对缓解国家能源压力和环境污染具有重要意义。为了实现风帆回转运动的自动化,根据电液比例泵控马达系统的原理,设计了一种风帆回转液压系统,并建立了系统的数学模型。使用Matlab/Simulink对系统进行了仿真分析,仿真结果表明,该系统在PID控制下,当无负载干扰时,风帆转角可以被精确控制;当对系统加入100~220 k N·m大小的负载力矩的干扰时,系统能快速恢复到稳定状态且控制精度不变,控制性能满足风帆回转运动的需求。
The research and application of modern sail navigation technology is of great significance to ease the national energy pressure and environmental pollution. In order to realize the automation of sail rotation, a sail hydraulic system is designed according to the principle of electro-hydraulic proportional pump motor system. The mathematical model of the system is established. The simulation analysis of the system was carried out by using Matlab / Simulink. The simulation results show that the steering angle of the sail can be precisely controlled under the PID control without load disturbance. When the load torque of 100 ~ 220 kN · m is added to the system, The system can quickly return to a steady state with the same control accuracy, and the control performance meets the requirement of sail slewing motion.
