Understanding how to apply theory of closed loop control to electrohydraulic servo systems. Deepen the knowledge of used hydraulic components. Understanding of industrial control systems in particular classical single-input-single-output servo control systems: hydraulic, and electro-mechanic. To know basic physics and interaction among components of a servo control and behaviour of the system in both time domain and frequency domain. Reference tracking, disturbance rejection, and robustness. To know different control strategies. Numerical simulations is also used.
