摘要
喷水推进是一种广泛应用的船舶推进技术,对其进行建模和仿真分析具有重要意义。首先介绍喷水推进及其倒航机构的工作原理,然后对某船舶喷水推进器中的倒航控制系统进行了建模,同时给出了系统传递函数,并且利用滑模控制算法对系统跟踪性和抗干扰性进行了仿真。仿真结果表明,和传统PID控制相比,滑模控制具有更好的设定值动态跟踪性能和鲁棒性。
Modeling and simulation of the marine water-jet propulsion system is significant for the increasing applications of the system in modern sea carriages. In this contribution, the mechanism model of the reverse control for water-jet propulsion system is established. The transfer function of the closed-loop control system is presented. Sliding mode control is investigated both for improving trajectory tracking and disturbance rejection performance. Simulation results demonstrate that the sliding mode control outperforms the conventional PID strategy.
