Design of ship automatic control system in fuzzy mathematics theory

传统船舶控制系统的的控制逻辑存在隶属关系量模糊问题,出现船舶无法自动控制指令动作滞后的现象。因此,提出模糊数学理论的舰船自动控制系统设计。针对问题产生根源在于隶属量的模糊计算逻辑,对现有的控制系统的硬件参数进行调整,通过对硬件的调整实现对将要引入算法的支持。引入PID自动控制算法,对船舶的控制量进行重组计算。然后,通过引入的模糊算法对计算的控制量进行隶属量的模糊逻辑计算,完成对传新的船舶自动控制系统的设计。最后,通过对比实验的方式,将模拟数据导入设计的系统并记录结果。结果表明,提出设计的系统具有集成度高、控制能力强、控制计算准确率高的优点。

There is a fuzzy problem of membership relation in the control logic of traditional ship control system,and there is a phenomenon that the ship can not automatically control the command action lag.Therefore,the design of ship automatic control system based on fuzzy mathematics theory is put forward.In view of the root of the problem lies in the fuzzy computing logic of membership quantity,firstly,the hardware parameters of the existing control system are adjusted,and the support of the algorithm will be introduced through the adjustment of the hardware;then,the PID automatic control algorithm is introduced to reorganize the control quantity of the ship;then,the fuzzy logic calculation of the membership quantity of the calculated control quantity is carried out through the introduced fuzzy algorithm,and the new ship is transmitted to the new ship.Design of automatic control system.Finally,through the comparative experiment,the simulation data are imported into the designed system and the results are recorded.By comparing with the traditional ship control system data,it is proved that the proposed system has the advantages of high integration,strong control ability and high accuracy of control calculation.
