Abstract

Large scale systems, such as interconnected power systems, need to be described in a more accurate form than in the past allowing the overexploitation of system resources. Not negligible nonlinear phenomena increase computational complexity especially for what control system design concerns. Classical control design, based on linearization techniques has become no more suitable to take into account strong nonlinear effects and unmodeled dynamics while input-output feedback linearization shows computational difficulties as the order of the system to be linearized increases. In this paper the classical feedback-feedforward technique for linear systems has been applied to a particular cascade connection of an input-output linearized system feeded by a linear system. The proposed approach achieves perfect tracking for the linearized model and an overall reduction in computational effort.
