本文介绍并论证了一种简化的模糊控制算法。常规的模糊控制算法要对误差E(i)和误差变化量EC(j)的每一组合做21句求最大、最小的三元联运算,然后再求21句的并,计算量相当大,编程也较困难。简化算法较之通俗、易懂、直观、简便。用BASIC语言编程在SYM-1微型机上通过,不到一分钟即得到与常规算法完全相同的模糊控制表,时间为常规算法的十分之一,用手算也能很快得到结果。简化的模糊控制算法步骤为: (1)先分别找出E和EC赋值表的每一个等级中最大从属度及其对应的模糊状态
This paper presents and demonstrates a simplified fuzzy control algorithm. The conventional fuzzy control algorithm needs to find the largest and the smallest ternary conjunctions for each combination of the error E (i) and the error variation EC (j), and then calculates the sum of 21 and the calculation amount is quite large, Programming is also more difficult. Simplified algorithm than the popular, easy to understand, intuitive and easy. BASIC language programming in the SYM-1 microcomputer through, less than a minute to get exactly the same with the conventional algorithm fuzzy control table, one-tenth of the time for the conventional algorithm, the results can be obtained by hand. The simplified fuzzy control algorithm steps are as follows: (1) First find out the largest subordinate degree and its corresponding fuzzy state in each level of E and EC assignment table
