The theory and associated numerical techniques for the Multiple Input Multiple Output Compensator Improvement Program are presented. This algorithm is applicable to the design of the feedback compensation matrix for linear time-invariant control systems with plants possessing multiple control inputs and multiple outputs. The algorithm discussed in this paper differs from the more common multiple-loop break design methods in that each control loop is individually broken. The design specifications that the Multiple Input Multiple Output Compensator Improvement Program attempts to achieve are single input, single output, openloop frequency response oriented. The practical utility of the program is illustrated by a launch vehicle example.
