摘要
船舶的动态特性具有强耦合、非线性、大时滞和大惯性等特点,并且风、流和浪等外部随机干扰也随着不同海况发生很大的变化,推进控制很难用精确的数学模型进行描述。根据船舶螺旋桨的推进特性,在阐述小型船舶电力推进系统的组成及运行特点的基础上,分析了推进电机控制的要求。采用矢量型变频器,设计了以菲尼克斯PLC为核心的控制系统,分析了系统的硬件配置和软件编程。实验结果表明,设计的控制系统能够满足控制功能要求,改善控制性能,提高系统控制可靠性。
Because of the ship dynamic characteristics,featuring high coupling,nonlinearity,large delay and large inertia etc.,and significantly changing exterior random disturbance from wind,waves and current in different sea conditions,it is difficult to describe the control of electric propulsion system with an analytical mathematical model.The composition of electric propulsion system for small ships and its running features are described considering the characteristics of ship propellers,and the requirements concerning propulsion motor control are analyzed.A control system based on a vector inverter and Phoenix PLC is presented with description of the hardware configuration and software programming.Experimental results show that the design satisfies the control function requirements and has good reliability.
