cze	Experimentální identifikace hydraulicko-pneumatické soustavy	Článek je věnován experimentální identifikaci hydraulicko-pneumatické soustavy. Soustava je tvořena dvěmi páry vodních nádrží, které mají pneumatické objemy nad hladinami vzájemně propojené. Tyto pneumatické obvody tvoří vazby mezi oběmi sekcemi. Pro určení parametrů modelu byly použity naměřené časové i frekvenční odezvy. Model je ve tvaru spojitých přenosů a byl verifikován pomocí odezev na skokové změny vstupních veličin.

eng	Experimental Identification of Hydraulic-pneumatic Process	Paper deals with experimental identification of hydraulic-pneumatic process. Process consists of two pairs of water tanks, which have air spaces above water levels connected together by pneumatic volumes and valves. These pneumatic connections create cross coupling between both sections. Process has own electrical power unit for signal data processing, which is connected with Real-Time Toolbox MATLAB and the environment Simulink running on PC. Both measured time and frequency responses were used for model parameters estimation. The model was in form of continuous time transfer function. Both models were verified and compared on measured step responses.	Laboratory model, multivariable system, experimental identification, frequency responses, MATLAB
