Multiple Model Adaptive Control Using Dual Youla-Kucera Factorisation

Multiple Model Adaptive Control Using Dual Youla-Kucera Factorisation

We propose a multi-model adaptive control scheme for uncertain linear plants based on the concept of model unfalsification. The approach relies on examining the ability of a precomputed set of plant-controller candidates and choosing the one that is best able to reproduce observed inand output signal samples. The ability to reproduce observations is measured as an easily computable signal norm....

A Youla-Kucera parametrized adaptive feedforward compensator for active vibration control with mechanical coupling

Most of the adaptive feedforward vibration (or noise) compensation systems feature an internal ”positive feedback” coupling between the compensator system and the correlated disturbance measurement which serves as reference. This may lead to the instability of the system. Instead of the standard IIR structure for the adaptive feedforward compensator, the paper proposes a Youla-Kucera parametriz...

Sample Pages to Be Followed Exactly in Preparing Scripts Adaptive Control of a Coupled Drives Apparatus Using Dual Youla-kucera Parametrization

An adaptive algorithm based on the dual Youla-Kucera parametrization is introduced enabling simple closed-loop identification and adaptation of a class of symmetric MIMO systems. The methodology exploits the algebraic approach to control system design. Necessary conditions for usage of the developed method are discussed and results are presented for the case of coupled drives control. Copyright...
