High Order Sliding Mode Observer-Based Output Feedback Controller Design For Electro-Hydraulic System

A perturbed linear system with property of strong observability ensures that there is a sliding mode observer to estimate the unknown form inputs together with states estimation. In the case of the electro-hydraulic system with piston position measured output, the above property is not met. In this...
