A novel adaptive-gain technique for high-order sliding-mode observers with application to electro-hydraulic systems

•A novel technique for adaptive gain selection in high-order sliding mode observers.•State and disturbance estimation on a hydraulic actuator is experimentally evaluated.•Comparison with fixed gains and a classic gain adaptation technique is made.•The performance are comparable or superior to other...
