Abstract: This paper presents a robust control method for multi-input multi-output (MIMO) non-linear systems with uncertain hysteresis using operator-based robust right coprime factorisation approach. In details, a new operator-based robust control system design is proposed for MIMO non-linear plants preceded by hysteresis and some sufficient conditions are proposed. By using the obtained conditions, the controlled system is robustly stable and the desired output tracking performance can be realised. Finally, simulation is done to validate the effectiveness of the proposed control design method.
