摘　　要：研究模糊插值控制器的选择问题,从理论与仿真两方面对模糊插值控制器进行了比较.基于控制精度概念,得到了分段线性插值设计的单输入单输出(SISO)模糊系统控制精度阶数是2,样条插值设计的SISO模糊系统控制精度阶数是4.仿真结果表明,在相同的控制规则下,模糊样条插值控制器具有更高的控制精度.In the paper,the selection of fuzzy interpolation controller was investigated,and two kinds of fuzzy interpolation controllers in view of theory and simulation were compared.By using the concept of control precision,we received that the control precision order of SISO fuzzy system was two based on piecewise linear interpolation,and the order was four which was based on spline interpolation.The simulation results showed that,under the same control rules,the fuzzy spline interpolation controller had higher control precision.
