“…The application of a robust sliding mode control strategy to the impedance control of a hydraulic excavator is discussed in [10]. The authors of [11] use a transfer function approach in combination with linear controllers to analyze the stability of an electrohydraulic impedance system. Up to the knowledge of the authors in this context no works can be found which directly account for the nonlinear characteristics of electrohydraulic systems.…”
