摘　　要：介绍了一个多变量模糊预报式解耦控制器的设计理论，通过计算机进行了仿真研究，其结果表明它算法简单，解耦效果比较好。Although we in 1992 succeeded in obtaining a satisfactory design of multivariab)e fuzzy-compensating-decoupling-control for a Chinese industrial system, it requires largeamount of computation. In this paper, we propose an improved method that is simpler andrequires much less computation.In this paper we present eqs. (1) and (2) that make our method much simpler. In 1992we had to make use of a very large table, whose much simplified form is given in Table 3. Bydiscarding the less important portions of the said very large table, we obtain its core, calledby us fuzzy-prediction-control core, which, in turn, allows us to derive mathematicallyeqs. (1) and (2).we use our simplified method to do simulation study of control of an industrial system.The simulation results are presented in Figs. 2 through 5. Despite some errors unavoidable insimplifying the said very large table, our simplified method appears to give quite satisfactoryresults.
