Position control by hydraulic drives is recommendable if high forces, very fast response or a very compact solution are required. The convenient technology is closed loop servo or proportional control which provides excellent dynamics and precision if all components, i.e. the hydraulic cylinder, the proportional or servo valve and the position sensor have adequate accuracy and dynamical performance characteristics. But this technology has its downsides, namely, high component costs, high oil cleanliness requirements and bad efficiency. Even though efficiency is not always a critical issue from the energy cost perspective, particularly if that drive consumes low portions of the overall used energy, the cost and installation effort of the hyd...
