| 摘 要： | 建立了船舶减摇鳍控制系统数学模型,提出了一种模糊规则后件采用PID表达式的TS-PID模糊控制器模型,并推导出了输入采用正规模糊集、三角形全交迭隶属度函数时该模糊控制器的插值表达式,为实际应用提供了一种快速精确的控制算法。在此基础上,应用钝性定理研究获得了减摇鳍TS-PID模糊控制器闭环系统IO稳定的充分条件,并探讨了利用遗传算法进行优化设计的方法。最后通过计算机仿真,验证了减摇鳍TS-PID模糊控制器的优越性。

| Abstract: | An optimal design approach of TS-PID fuzzy controllers for ship fin stabilizer control is proposed in this paper. TS-PID fuzzy controllers are a class of T-S fuzzy controllers with PID expression consequents. The interpolation model of a typical TS-PID fuzzy controller is presented. It can be used to develop a fast and precise control algorithm in application. By using the passivity theorem, a sufficient condition for an IO stable TS-PID fuzzy controller applied to ship fin stabilizer control has been obtained. The optimal design procedure of a TS-PID fuzzy controller for ship fin stabilizer control is also discussed in detail by means of Genetic Algorithm. The simulation results of a ship fin stabilizer control system show the advantages of TS-PID fuzzy controllers. |
