A general algorithm for evaluating the normalised integral-square-error criterion of controllability is presented as a function of the parameters of a feedback control system. Pure time delays are incorporated as Pade polynomial approximations and a matrix solution of the integral using Gaussian elimination avoids the need for standard integral tables.
