基于广义预测控制的船舶可调桨网络控制系统研究

Study on the ship controllable pitch network control system based on the generalized predictive control

可调螺距螺旋桨(CPP)控制系统是船舶推进系统的重要子系统.随着船舶推进系统在响应速度、操纵性能等方面的要求不断提高,CPP控制系统已从传统的控制系统发展到分布式的网络控制系统,而网络控制的引入必然产生不确定的网络时延.因此,采用支持向量机、广义预测控制和队列机制的混合控制方法设计了网络控制器,有效地补偿网络时延对CPP控制系统产生的不利影响.

Controllable pitch propeller （CPP） control system is the subsystem of ship propulsion system. Along with ship propulsion system better requests of response speed and handling quality, it has been developed from traditional control system to distributed networked control system, while network control has inevitably caused indefinite network delay. Thus networked controller has been designed based on combination of support vector machine, generalized predictive control and queuing strategy, which couM effectively compensate the adverse effects of network delay.
