Development and Testing of a Hydrotronic Control System for a Prototype Test Bench for Vibration Isolation Systems

This paper presents the virtual prototyping of a hydrotronic hydraulic actuator position control system. The hydraulic actuator is part of a test bench for pneumatic vibration isolation systems. It should force a sinusoidally variable movement of the device platform. The amplitude and frequency of this movement are set and changed according to testing needs. The control system under development was based on the Danfoss Plus + 1 series proportional directional valves and controllers. The article focuses on discussing the synthesis of the control algorithm and presenting the simulation method used to predict the dynamic capabilities of the designed system.
