【摘要】 根据减摇鳍的控制原理,讨论了减摇鳍数字控制器中航速调节单元的设计.在分析船舶计程仪原理的基础上,根据减摇鳍数字控制器的特点,设计了航速信号采集的硬件接口单元.在软件设计中,采用多中断协调机制,充分结合航速多普勒计程仪的脉冲信号特性,在不影响控制器实时性的基础上,实现了航速信号的采集和航速调节的软件设计.通过实船装备检验,效果良好.更多还原

【Abstract】 Based upon the control principle of fin stabilizer,the design of adjusting unit according to ship speed was discussed.After analyzing the principle of log and characteristic of digital controller of fin stabilizer,the hardware interface of collection of ship speed signal was designed.As for its software,by making use of the character of pulse of Doppler log,the multiinterruption coordinatie method was proposed to for collection and adjustment according to the ship speed.The results shows that the way is excellent and does not affect the realtime requirement of the system.更多还原
