The Independent Modal Space Control (IMSC) method avoids control spillover generated by conventional control schemes such as Coupled Model Control (CMC) by decoupling the large flexible space structure into independent subsystems of second order and controlling each mode independently. The IMSC implementation requires that the number of actuators be equal to that of modeled modes, which is in general very huge. Consequently the number of required actuators is unrealizable. Two methods are proposed for the implementation of IMSC with a reduced number of actuators. In the first method, the first m modes are optimised, leaving the last (n-m) modes unchanged. In the second method, generalized inverse matrices are employed to design the feedback controller so that the control scheme is suboptimal with respect to IMSC. The performance of the proposed methods is tested by performing computer simulation on a simply supported beam. Simulation results are presented and discussed.
