摘要

The study deals with control of interface of hardware-in-the-loop-simulator for hydro-mechanical machines. In the proposed form a real-time simulator of hydraulic system can be connected with a mechanical hardware by flow-pressure interface realized by high-bandwidth servo or proportional valves with flow feedback control. A flow control method based on inverse valve model and flow feedback with Pi-controller is proposed and studied in z-domain. Model in z-domain for a simple complete HIL-simulator is derived and utilized in analyzing the properties of the proposed controller.
