On the implementation of the independent modal-space control method

Abstract

Some implementation characteristics of the Independent Modal-Space Control method are considered. It is shown that the control method is completely robust with respect to modeling errors and plant truncation effects. The globally optimal control of distributed systems requires distributed actuators. Instead of using distributed actuators, the distributed control is approximated with discrete actuators. Since the distributed control is closely approximated, the closed-loop poles are computed as a perturbation of the distributed control. The discrete actuators are located such that the control spillover is minimized.
