摘　　要：研究Norrbin非线性船舶运动航向系统的稳定控制问题。在定义有效最大交叠规则组的基础上,应用并行分布补偿(PDC)方法设计出使模糊系统全局渐近稳定的控制器,并提出和表明了一个新的判定闭环T-S模糊系统稳定的充分条件,该条件降低了以往方法的保守性和难度。以大连海事大学"育龙"轮为对象进行仿真研究,结果证明所设计的控制器是有效的。The stable problem of nonlinear Norrbin system of ship motion course was discussed. Firstly, based on the definition of the efficient maximal overlapped-rules group, a fuzzy controller was designed to acquire globally asymptotical stability for fuzzy system with the method of parallel distributed compensation （PDC）. Then a new sufficient condition to check the stability of closed-loop T-S fuzzy system was proposed and proved This condition is less conservative and difficult than the former approaches. At last, the results of the simulation of the ＂Yu Long＂ ship owned by Dalian Maritime University show that the designed controller is effective.
