【摘要】 减摇水舱是一种重要的减摇装置，尤其是在船舶航行在低航速情况下能有效的进行减摇，克服了减摇鳍在低航速情况减摇效果较差的缺点。因此，在目前我国还没有进行减摇水舱装船前，为更好地进行减摇水舱的减摇性能研究，需要设计一种模拟实船运动的实验装置---船舶横摇运动试验台架来检验水舱的效果。本论文主要是研究DSP在船舶横摇运动试验台控制系统设计中的应用问题。其主要内容包括： (1)通过计算机对不同的海况进行仿真，得出不同的海况下不同的波浪的干扰模拟力矩M_w。 (2)船舶横摇运动试验台的物理结构并对元件的选取，同时对系统的稳定性进行了分析。对试验台的数字控制器进行了经典PID设计，同时对系统进行仿真。 (3)对控制系统进行了硬件和软件设计。硬件主要是由DSP(TMS320F240)组成的最小系统。软件包括控制系统算法和系统初始化及A／D、D／A转换程序、RS-232串口通信程序和PDPINT中断保护程序。 (4)设计了信号偏置电路和伺服阀驱动电路。更多还原

【Abstract】 Anti-rolling tank is an important stabilization equipment on watercraft and it has been popularly used to reduce ship rolling motion especially when the speed of ship is very slow and fin stabilizer could not take in effect because anti-rolling tank is very useful. At the present, all the anti-rolling tank is taken from abroad. In order to design the anti-rolling tank and equipped it on the watercraft, an experiment equipment is needed. The equipment can be used to emulate the ship motion and test the efficiency when the ship equips the tank. In the dissertation, it research on how use the DSP to control experiment equipment system. Some works have been done and they are:(1) Using computer simulate sea wave in different situation, and the differentdisturbed moment Mw has been got.(2) Selecting the components of the experiment equipment of ship rolling motion. Getting the transfer function of the system and analyssing it’s robust. Designing digital PID control and simulating the system after the control been added.(3) Designing software and hardware for the control system. The hardware is a minister system and the processor is DSP(TMS320F240).The software includes some parts : PID arithmetic progranu System’s initialize program> A/D and D/A transfer program^ RS-232 serial communication program and PDPINT(Power Driver Protection Interrupt) program.(4) Designing the sign transfer board and the driver board of electric and hydraulic servo mechanism.更多还原
