✦ Synopsis

A two-stage observer-based controller design of discrete two-time-scale ( D TTS) systems is presented in this paper. The necessary and sufficient conditions for this kind of controlled system are all addressed. The robust slow-observer-based (SOB) controller is investiyated in detail. For a fast samplin 9 rate model, prediction type observer-based controller and SOB controller are proposed. Both prediction type and current estimation type observer-based con troller and SOB controllers are developed for a slow sampling rate model of D TTS.2vstems. A twin-engine aviation aircraft is utilized to illustrate the derived schemes.
