- The accurate and predictive control of complex, non-linear systems, with discrete-time interval outputs, encountered in many engineering applications, requires adaptive observers to monitor states and provide diagnostics. This paper is significant because it represents the first application of a Continuous-Discrete Time-Observer (states and disturbances) to the control of an Electro-Hydraulic Valve Actuation (EHA) system. A Lyapunov function, based on small gain arguments is used to verify the convergence of the continuous-discrete time observer. This represents the first time that such observers were designed and experimentally validated on an EHA system and demonstrated good efficiency in tracking performance and disturbance estimation.
