Self-Tuning Control of an Electro-Hydraulic Actuator System [PDF]

International Journal on Smart Sensing and Intelligent Systems, 2011
Abstract Due to time-varying effects in electro-hydraulic actuator (EHA) system parameters, a selftuning control algorithm using pole placement and recursive identification is presented. A discrete-time model is developed using system identification method to represent the EHA system and residual analysis is used for model validation.
