Abstract
A demonstration that feedback control of systems with redundant contro ls can be reduced to feedback control of systems without redundant con trols and control allocation is presented. It is shown that control al location fan introduce unstable zero dynamics into the system, which i s important if input/output inversion control techniques are utilized. The daisy chain control allocation technique for systems with redunda nt groups of controls is also presented. Sufficient conditions are giv en to ensure that the daisy chain control allocation does not introduc e unstable zero dynamics into the system. Aircraft flight central exam ples are given to demonstrate the derived results.
