The original ITAE (stands for Integral of Time multiplied by Absolute Error) coefficient table was drived by D. Graham and R.C. Lathrop through an analog computer. The table has been widely adopted as a standard design tool in most undergraduate level control engineering text books. However, the optimality of these coefficients has been questioned by several researchers. This code provides a means to re-calculate these coefficient using more advanced numerical optimization techniques in digital computers.
