力伺服波浪补偿器广泛应用于海洋工程领域,研究力伺服波浪补偿器的控制系统具有重要意义。建立了其数学模型,运用前馈复合控制方法消除作用在液压马达输出轴的外负载力矩的扰动干扰。基于消去扰动干扰的系统的数学模型,分析了系统的稳定性、能观性、能控性,运用极点配置方法对系统的控制性能进行优化,得到反馈矩阵。通过仿真验证了优化后系统的控制性能达到了优化设计目标。
Force Servo Heave Compensator is widely used in the field of ocean engineering, so the study of the control system of Force Servo Heave Compensator is of great significance. First of all, establish its mathematical model, using feed-forward compound control method to eliminate the disturbance interference that the load torque disturbance acting on the output shaft of the hydraulic motor. Based on the mathematical model of disturbance interference elimination system, analyzes the stability, the observability the controllability of the system to prepare for the control performance optimization. Then, using pole assignment method to optimize the control performance of the system, get feedback matrix. Finally, the control performance of the optimized system is verified by the simulation, achieving the target of optimization design.
