“…e variation of the input error e c , the linguistic variables are taken as E C , the fuzzy domain is bigger negative, smaller negative, zero, smaller positive, and bigger positive (abbreviated as {NB, NS, ZE, PS, PB}), the basic domain is [−60, 60], the discrete domain is taken as [−3, 3], and the quantization factor is taken as 1/20. e output quantity step s, the linguistic variables are taken as S. e fuzzy domains are small, relatively small, medium, relatively big, and big (abbreviated as {S, RS, M, RB, B}), the basic domain is [10,50], and the discrete domain is [1,5]. e quantization factor is 1/10.…”
