Tracking in parametrically undefined linear systems

Abstract

Summary form only given. An approach to tracking controller design for single-input-single-output linear systems in the presents of unstable zero-dynamics and parametrically undefined mathematical model of the plant is proposed in the paper. It is assumed also that there is incomplete knowledge about ecosystem characteristics and state vector of the system. The presented approach is based on the theory of sliding motion control, state vector observer design and online identification of unknown parameters.
