Dynamic positioning is one of the essential functions of ocean tugs and a Joystick controller is widely utilized for keeping a desorable position under munual control. Inthe present report , an attempt is done to develop the joystick controller for a typical ocear tug with two controllable pitch propellers,two flap rudders and a bow thruster.At first, the results of the captive model tests carried out in low speed and shallow water conditions is reported and the mathematical model of maneuvering motions of ships with relatively large lateral motions is developed.Second, The procedure to keep a desirable position is discussed and the recommendable combnations of several control devices are proposed.Lastly, real-time simulation study is carried out for evaluating the effectiveness of the joystick control system and the basic method to design such systems are proposed.

动态定位是远洋拖船的基本功能之一，操纵杆控制器被广泛用于在手动控制下保持理想的位置。在本报告中，尝试开发用于典型海洋拖船的操纵杆控制器，该拖船具有两个可调螺距螺旋桨、两个襟翼舵和一个艏侧推器。报告了条件，并建立了具有较大横向运动的船舶操纵运动的数学模型。其次，讨论了保持理想位置的程序，并提出了几种控制装置的推荐组合。最后，进行了实时仿真研究来评估操纵杆控制系统的有效性，并提出了设计此类系统的基本方法。
