基于AMEsim-Simulink联合仿真的风帆液压控制

针对风帆驱动控制系统提出了差动缸液压控制方案,利用AMEsim软件建立液压系统仿真模型,再结合Simulink软件在控制系统设计方面的优势,对风帆驱动系统进行联合仿真研究。通过联合仿真比对了常规阀控非对称缸与本文作者提出的差动缸控制系统,验证了本文作者提出的差动缸控制风帆系统的优越性。分析了某一定常力负载下的阶跃动态响应及风帆所受实际变化负载力状态下的跟踪角度曲线,仿真表明该控制方案对风帆驱动控制的有效性和可靠性,可为风帆助航船风帆控制提供技术支持。

Hydraulic Control of Sail Based on AMEsim-Simulink Co-Simulation

The differential cylinder hydraulic control system is proposed according to requirements for sail drive control. Co simulation research for sail control system was carried out with advantages in integration of AMEsim and Simulink software design which established hydraulic system control simulation model. With use of Co-simulink, the advantages of differential cylinder control system of the sail were verified by comparison of conventional valve control asymmetrical cylinder and differential cylinder control system proposed. The step dynamic response under a certain constant force load and tracking angle curve under the condition of the actual force load of the sail were analyzed. The simulation shows that the control scheme of the sail drive control is effective and reliable, which can provide technical support for control of sail-assisted ships.
