In a feedback control scheme, gv = gm = 1, gp = exp(-0,25s)/(s+1), gd = exp(-0,25s)/(td*s+1) and exp(-teta*s) = 1 - teta*s, obtain gc(s) through direct synthesis method knowing that the regulatory answer is c/l = kd*s*exp(-teta*s)/(tc*s+1)^2, expressing the pid controller parameters in function of those in gp, gd and c/l.
