Two methods are presented for grouping actuators while minimizing performance degradation in distributed control systems with saturation constraints. Method one is based on an open-loop performance metric using controllability Grammians. The grouping problem can be converted into a graph partitioning problem which admits a solution via linear matrix inequality (LMI) optimization techniques. Method two is based on closed-loop optimal control performance for saturating control systems. In this case, we find that grouping the actuators allows on-line control design to account for control saturation. It was determined that the grouping problem is insensitive to changes in actuation authority.
