INNOVATIVE APPROACH TO COMPENSATOR DESIGN.

A computer-aided-compensator design technique is presented for a control system, with open loop frequency response by n discrete frequency points which result in n functions of the compensator coefficients. Several of these functions are chosen so that the system specifications are properly portrayed; then mathematical programming is used to improve all of these functions which have values below minimum standards. A mathematical programming tool for aiding in the solution of the problem is developed. This tool is called the constraint improvement algorithm. Then for applying the constraint improvement algorithm, generalized gradients for the constraints are derived.
