Abstract

Electro-hydraulic systems are an essential part of modern industry. Nonetheless, these systems have input constraints and must be controlled under model uncertainties and disturbances using a saturated control signal. In this study, a saturation compensation scheme is developed using an adaptive fuzzy logic based methodology via the use of Lyapunov based synthesis and analysis method. The proposed methodology ensures uniform ultimate boundedness of the error signals despite the uncertainties in the system dynamics. The effectiveness of the proposed methodology is demonstrated through numerical simulations.
