✦ Synopsis

This paper first finds that the high frequency (ω) periodic controller suggested in for fixed mode removal, and pole and zero placement, of a class of decentralized systems (A, B i , C i ) all the strongly interconnected channels of which satisfy C i B i = 0, causes large, O(ω), oscillations in the outputs. Next it proposes an alternative controller, a dual of the above, that achieves the compensation with oscillations of O(1) only.
