Periodicity | yearly recurring course |
Language of instruction | German |
Abstract | Introduction to the physical and technical basics of oilhydraulic and pneumatic systems and their components as pumps, motors, cylinders and control valves, with emphasis on servo- and proportional techniques and feedback- controlled drives. In parallel an overview on application examples will be given |
Objective | the student - can interpret and explain the function of an oilhydraulic or pneumatic system and can create basic circuit concepts - can discribe the architecture and function of needed components and can select and design them to desired properties - can simulate the dynamical behaviour of a servohydraulic cylinder- drive and can design an optimal state-feedback-control with observer |
Content | Significans of hydraulic and pneumatic systems, general definitions and typical application examples. Review of important fluid-mechanical principles as compressibility, flow through orifices and friction losses in line-systems. Components of hydraulic and pneumatic systems as pumps, motors, cylinders, control valves for direction, pressure and flow, proportional- and servo-valves, their function and structural composition. Basic circuit concepts of hydraulic and pneumatic control systems. Dynamical behaviour and state-feedback-control of servohydraulic and -pneumatic drives. Exercices Design of a oilhydraulic drive-system Measurement of the flow characteristic of an orifice, a pressure valve and a pump. Simulation and experimental investigation of a state-feedback-controlled servo-cylinder-drive. |
