Learning Outcomes

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.
