摘　　要：该文针对目前某些模糊控制系统在控制过程中精度比较低的问题,将模糊控制系统离线得到的模糊控制表与双线性插值算法结合起来,提出一种新的基于在线插值的模糊控制系统的设计方法,用此方法使模糊控制器输入、输出值保持连续变化,以此来克服控制器因输入输出量化所造成的调节死区与可能出现的稳态等缺点,从而来达到提高模糊控制系统控制精度的目的。在某舰船控制系统的仿真例子说明了此方法的有效性。The control accuracy of some fuzzy control systems in control processes is lower. To solve the problem, the fuzzy control table obtained in off - line control is combined with the bilinear interpolation algorithm to create a new design method of fuzzy control system based on linear interpolation. This method can make the value of inputs and outputs of a fuzzy controller changeable continuously. The disadvantages of an ordinary fuzzy control system, lower control precision, and steady - state flutter which may appear because of quantifying the inputs and outputs of the controller, are overcome by using the presented method. A simulation example for a ship control system is given to show the effectiveness of this method.
