Model Based Development Using Hardware in the Loop Simulation for Servo Press Machine

This paper presents a proposal of Model-Based Development (MBD) for efficient development of a control method of a large industrial machine such as a press machine using Hardware-In-the-Loop Simulation (HILS) verification system that can accommodate combined phenomena in mechanical, electrical, and control fields. The proposed HILS verification system consists of an actual servo amplifier, an actual controller, and a real-time simulator with machine model, motor models, and electric circuit models installed. It is possible to optimize the control method and parameters for various operating conditions. The proposed method was applied to the design and verification of a control method that suppresses fluctuations in the DC-link voltage and motor current during the press operation of a press machine driven by a 75 kW servo motor. Its effectiveness was confirmed.
