摘要
可调螺距螺旋桨(简称可调桨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和操纵性能等方面提出的更高要求,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,本文采用支持向量机+广义预测控制+队列机制的混合控制方法设计了网络控制器。仿真结果表明,该控制算法能有效地补偿网络时延对CPP控制系统的影响,使之具有较好的稳定性和鲁棒性。
Controllable pitch propeller （for short： CPP）control system is the subsystem of ship propulsion system. Along with the ship propulsion system better requests of the response speed and handling quality, it has been developed from the traditional control system to the distributed networked control system, while the network control has inevitably caused the indefinite network delay. Thus the networked controller has been designed based on the combination of support vector machine, generalized predictive control and queuing strategy. Simulation results show that the algorithm could effectively compensate the influence of network delay, which could make it posses of better performance of stability and robustness.
