摘要
本文应用微机控制系统的数字直接设计原理，在求得船用主柴油机Ｚ传递函数模型基础上，设计了主柴油机转速直接数字控制（ＤＤＣ）系统，得出了ＤＤＣ系统控制器的Ｚ传递函数和微机实现的递推算法。对某船主柴油机和推进器形成ＤＤＣ仿真系统，进行仿真运行。
The direct digital control(DDC) system for main diesel engine speed is developed according to the theory of direct digital design of computer based control system and on the basis of the model of Z transfer factor of ship's main diesel engine. The Z transfer factor for DDC system controller is derived and computer based reckoning is realized. A DDC simulation system is developed for the main diesel engine and propeller of a ship for carrying out simulated operation.
