Subject aims expressed by acquired skills and competences

The goal of the subject is to obtain deeper knowledge of servo mechanisms compared to the engineering study. Besides the analysing the dynamic characteristics of servo mechanisms, there are studied synthesis methods of control circuit of servo mechanisms, mainly with regard to the dynamic stability of the control circuit. There is studied the problematics of passive resistance of hydraulic motors at low speed (so-called stick-slip) in the field of electro-hydraulic servo mechanisms.

Summary

The Ph.D. student is acquainted in the subject “servo mechanisms” with the definition, composition and types of servo mechanisms, and focuses in detail on electrohydraulic servo mechanisms. He will deal in detail with construction, function, static characteristics and dynamic properties of individual members of electrohydraulic servo mechanisms: hydraulic motors, servo valves, sensors, controllers. He is acquainted in the area of dynamics of servomechanisms in detail with the ways of describing dynamic behaviour of members of servo mechanisms, with simulation programs focused on simulation of dynamic behaviour of servo mechanisms, with synthesis methods of speed and position servo mechanisms, using computer methods to solve problems, with dynamic stability of control systems of servo mechanisms and possibilities of increasing the dynamic stability of servo mechanisms.
