摘　　要：调速系统是船舶主机遥控系统的核心组成部分,船舶主机性能优劣及寿命很大程度上取决于其调速系统的性能。分析船舶主机调速系统的特点,研究了基于径向基函数(RBF)神经网络自整定非线性PID的主机转速控制,基于内模原理的偏差重复补偿PI的主机油门控制。讨论了PID参数随偏差变化的规律,控制对象的Jacobian辨识和主机油门的重复控制补偿,并分别进行了仿真。结果表明,本文设计的非线性自整定重复控制补偿调速器在充分考虑偏差特性的情况下,有效提高系统的动态精度和抑制扰动的能力,改善主机运行的稳定性。Speed regulating system is the core partition of main engine （ME） remote control system, ME performance and life-span depend on the ME speed regulating system. Analyze characteristic of ME regulating system, study ME speed control based on radial basis function （RBF） neural network self-tuning with, and ME fuel rack displacement control error repetitive compensation PI based on internal model theory. Discuss PID parameters changing with the deviation, control object identification Jacobian, and ME fuel rack repetitive control compensation. The simulation result shows that nonlinear self-tuning repetitive control compensation speed governor improves the dynamic precision of system and the ability to restrain the load disturbance in case of error Characteristics, thus enhancing the stability of ME speed.
