摘　　要：船舶航速的稳定性主要取决于主机负荷调节系统的响应特性,为抑制负荷扰动,提高船舶航速的控制精度,提出了基于Lyapunov方法的船速复合误差调节器,并进行了稳定性分析,实现了船速自适应控制。在实验室条件下,建立了船速复合误差调节器半实物仿真系统。仿真结果表明,在系统模型不确定性的情况下,船速复合误差调节器能提高系统抗干扰能力和船舶航速的稳定性。The stability of ship speed is determined by the response characteristic of the main engine load regulation system. To restrain the load disturbances and to improve the control precision of ship speed, a ship speed hybrid error regulator （SSHER） was proposed based on Lyapunov approach. Its stability of SSHER was analyzed, and adaptation law of ship speed was implemented. In laboratory conditions, the hardware-in-loop simulation of SSHER was established. Simulation results show that SSHER can restrain the disturbances, and can enhance the stability of ship speed in case of system model uncertainty.
