Modeling of a Twin-rotor MIMO System Based on the States of the First-principles-model and the Identification-model

Abstract

This paper studies linear-time-invariant (LTI) modeling of a twin-rotor MIMO system based on the dynamical models derived from the first principles and identification experiments, motivated by building LPV (Linear Parameter Varying) models. The present method proposes using the states of the first-principle-model and the identification-model. Continuous-time local LTI models with a consistent state are obtained in the frequency domain. It is also shown that an LPV model is computed from the local models.
