for a PI compensator, the prefilter is, ) (G_{p}=frac{left(K_{I} / K_{p} ight)}{left(s+{ }^{K_{I}} / K_{p} ight)}) 

for a PI compensator, the prefilter is,

а) \(G_{p}=\frac{\left(K_{I} / K_{p}\right)}{\left(s+{ }^{K_{I}} / K_{p}\right)}\)


c) \(G_{p}=\frac{\left({ }^{K_{p}} / K_{I}\right)}{\left(s+{ }^{K_{I}} / K_{p}\right)}\)

d) \(G_{p}=\frac{\left(K_{I} / K_{p}\right)}{\left(s+{ }^{K} / K_{I}\right)}\)
