This thesis deals with the modeling and control of electohydraulic systems. On basis on an accurate nonlinear model, an innovative position control scheme is proposed.

Besides that, an original and innovative scheme for the coordinated motion control of multi-dof hydraulic systems is proposed. Such a control scheme, referred to as Delayed Reference Synchronization Control, aims at reducing the synchronization error by delaying the references of the inn

Humans can interact with their environment by tuning the properties of the musculoskeletal system to control force and impedance at the contact points with the environment.

For example, when chiselling a piece of rough wood, motor noise or involuntary movements can make the hand slip out of the desired track. When a single reaching movement is repeated in unstable dyn
