Predictive Control Structure for a Two-Mass Drive System with a Two-Layer Observer

This paper presents the control problem of a drive system with an electric motor and a finitely stiff shaft. In such a system, effective damping of torsional vibrations requires the use of advanced control structures. Such structures, in turn, require precise information about all state variables, and often also about the system parameters. To ensure effective damping of torsional vibrations, the paper proposes the use of a predictive control algorithm that cooperates with a two-layer observer. Coupling these two algorithms resulted in improved state variable waveforms, particularly for unknown initial states, and the imposition of more stringent state variable constraints.
