摘　　要：深海采矿船升沉运动模拟平台是用来模拟海浪作用下海上作业平台的升沉运动。为得到符合平台模拟实际运动中各项技术指标要求的控制算法,利用Labview界面仿真工具包SIT,针对深海采矿船升沉运动模拟平台的阀控非对称缸模糊自整定PID控制系统的实现过程,在Labview和Matlab/Simulink中进行了联合控制仿真,且建立了阀控非对称缸系统的非线性数学模型,设计了相应的模糊自整定PID控制器,把Matlab强大的控制仿真功能与Labview灵活、开放、"软件仪器"功能的特点很好结合,实现了优势互补,仿真验证了设计的控制算法的正确和可行。其可视性,方便的参数调整、输出界面效果等均为课题的设计与制造提供了便利,具有一定的实用价值。The heave motion simulation platform of deep-ocean mining vessel is dealt with. The control algorithm with all the indexes fitments of actual motion in platform stimulation is studied. Aiming at the fuzzy self-tuning PID control of deep-ocean mining controlled asymmetrical cylinder, the joint controlled simulation is carried out by using Labview and Matlab/Simulink. And mathematical model of valve controlled asymmetrical cylinder system is established. The corresponding fuzzy self-tuning PID is designed. The combination of the powerful controlled sinmlation function of Matlab and the flexibility, openness and softlstrument of Labview is obtained. The simulation results show the correctness and feasibility of designed control algorithm. The convenience of parameter adjusting and output interface performance, make it be useful for design and construction of prohaving certain practical value.
