Subject aims expressed by acquired skills and competences

Students will learn methods of electro-hydraulic analogy, circuits RLC. Their task will be to design hydraulic circuits, to solve them using numerical methods Matlab-Simulink and SimHydraulics. They will analyze the results, evaluate the accuracy by comparison the theory and experiment or possibly reconstruct the districts for better solutions. In applications they become familiar with the modeling of dynamic phenomena in the flow pipelines using methods of numerical analysis.

Teaching methods

Experimental work in labs


The course focuses on the issues of electrohydraulic analogy and solutions of RLC circuits by numerical methods using Matlab-Simulink-Simscape. Part of the course is a measurement of hydraulic variables of selected hydraulic and pneumatic circuits and develop proposals to solve them both statically and dynamically. Part of the course is devoted to the physical properties of fluids and their dynamic behavior.
