DSP在舰船推进汽轮机的电液控制系统中的应用

Application of DSP in electro-hydraulic control system of marine propulsion turbine

舰船推进汽轮机将化石燃料的内能转换为螺旋桨的机械能,为轮船提供前进的动力。由于汽轮机装载于船体的基座上,不仅受到船体振动、冲击的影响,还会受到海上恶劣气象条件的影响。因此,采用合理的舰船汽轮机控制系统具有重要的作用。本文针对舰船汽轮机的调速、调温等控制问题,采用数字信号处理器(DSP)技术设计了一种舰船推进汽轮机的电液控制系统,并对该电液控制系统的电液伺服阀、DSP控制卡等硬件和软件程序进行详细介绍。

The ship propulsion turbine converts the internal energy of fossil fuels into mechanical energy of propellers,providing the propulsion power for ships.As the steam turbine is loaded on the base of the ship,it is not only affected by the vibration and impact of the ship,but also affected by the bad weather conditions at sea.Therefore,it is very important to adopt a reasonable control system of marine steam turbine.According to the ship turbine speed and the temperature control problem,using digital signal processor(DSP) technology to design a ship propulsion steam turbine electro-hydraulic control system of the electro-hydraulic control system of electro-hydraulic servo valve,DSP control card and other hardware and software are introduced in detail.
