为保障船用柴油机在不同运行工况以及转速突变情况下的稳定运行，设计船用柴油机转速智能控制系统。该系统的上位机模块，依据柴油机模块中传感器采集的柴油机运行数据，下达柴油机转速智能控制指令，经由CAN总线收发机制，将该指令安全传送至电子调速模块；电子调速模块以电子调速器为主，引入转速自主学习主动抗扰控制模型，控制柴油机模块中的柴油机的循环供油量，以此实现柴油机转速控制。测试结果显示，该系统应用后3种运行工况下的柴油机转速波动率均低于0.03%、瞬时调速率均低于3.34%、恢复额定转速所需时间均低于2.14 s，具备转速控制的动态、快速响应能力，且转速的控制结果与额定的转速结果吻合程度较高。
In order to ensure the stable operation of marine diesel engine under different operating conditions and sudden changes in speed, an intelligent speed control system for marine diesel engine is designed. The upper computer module of the system, according to the diesel engine operation data collected by the sensor in the diesel engine module, issues the intelligent control command of the ship diesel engine speed, and safely transmits the command to the electronic speed regulation module according to the CAN bus transceiver mechanism. The electronic speed regulation module is mainly composed of electronic speed regulators, and the speed self-learning active disturbance rejection control model is introduced to control the circulating fuel supply of the diesel engine in the diesel engine module, so as to realize the speed control of the diesel engine. The test results show that the diesel engine speed fluctuation rate is lower than 0.03%, the instantaneous speed regulation rate is lower than 3.34%, and the time required to restore the rated speed is lower than 2.14 s under the three operating conditions after the application of the system. The system has the dynamic and fast response capability of speed control, and the speed control results are in good agreement with the rated speed results.
