Regulace polohy přímočarého hydromotoru pomocí proporcionálního rozváděče

Abstract

This bachelor thesis deals with the position regulation of linear hydraulic motor by proportional direction valve. The theoretical part is discussing proportional technology, linear hydraulic motors and servomechanisms. Hydraulic circuit with linear hydraulic motor and proportional directional valve was designed and assembled in the practical part. Hydraulic circuit was also designed with pressure sensors and position sensor of linear hydraulic motor, which are specified in the practical part. This thesis includes range stop of linear hydraulic motor, which stops on designated position set by different setting of a regulator. Position regulation of linear hydraulic motor was simulated by Matlab Simulink software. In the last part, the individual states of position in time for different regulator parameters settings and for different pressure set on hydraulic aggregator was interpreted.
