用矩形域二元分片双一次插值算法对原程序做了修改（说实话，原程序我没看懂）。用模糊控制算法，对于非线性系统和数学模型难以建立的系统来说更易理解和编程！-Rectangular domain with two yuan slice Dual time interpolation algorithm for the original program was revised (to be honest, I did not understand the original program). Fuzzy control algorithm for nonlinear systems and mathematical models is difficult to establish the system easier to understand and programming!
