state controller with observer, electrohydraulic system, dynamic processes modeling and simulationAbstract
This paper deals with the synthesis of state controller with observer for an electrohydraulic power transmission system. There is shown a method for synthesis of the state controller with observer and the realization for electrohydraulic system. The controller coefficients are obtained from preliminary defined performance definitions. The system has been modeled, and step responses curves are obtained from computer simulation. Main results are given in a few graphics.
