Abstract

A state-space model based on Laguerre filters is proposed to design an adaptive generalized predictive controller (GPC) for stable plants. A sufficient stability condition is derived to study the convergence and stability of the proposed controller in case of a plant-model match. Robustness conditions are also given for the case of plant-model mismatch. The results are applicable to GPC schemes based on moving average models. In the presence of plant-model mismatch, illustrative examples show the robustness of the controller and compare it with other GPC versions.
