摘要
通过AMESim和MATLAB/Simulink联合仿真的方法建立二次调节主动升沉补偿系统的仿真模型,模型加入了时变和非线性因素的影响,能较为真实地反映实际主动升沉补偿系统特性和实现各种控制策略。研究结果表明:采用具有双前馈补偿的串级PID闭环控制,提高了系统的升沉补偿精度;变量机构与二次元件斜盘配合的间隙等非线性因素会降低系统补偿精度;绞车的非线性摩擦力矩对补偿精度的影响较小。
AMESim and MATLAB/Simulink co-simulation method is used to establish the simulation model of the active heave compensation system with secondary adjustment.The model can reflect the characteristics of the actual active heave compensation system and achieve a variety of control strategies by adding time-varying and nonlinear factors.The simulation results show that the cascade proportional-integral-derivative(PID)closed-loop control with double feed forward compensation improves the heave compensation accuracy of the system.The nonlinear factors such as the clearance between the variable mechanism and the swash plate reduce the compensation accuracy of the system.The nonlinear friction torque of the winch has a little effect on the compensation accuracy.
