讲座题目：Challenges in Real-time Co-simulation and Cyber-physical Testing

主讲人: Prof. Francisco Javier González Varela

讲座内容：

  Model-Based System Testing (MBST) is emerging as a transformative technology that enables the experimental testing of components and algorithms from the early stages of the product development cycle. MBST integrates physical experiments with computer simulations to enhance the testing process, reduce costs, and accelerate product development cycles.

  Cyber-physical testing is one of the most promising and challenging applications of the MBST paradigm. In this approach, the physical device undergoing the test procedures is coupled with a virtual representation of its environment in a real-time setup. For example, the electric drive of an e-Powertrain can be tested against a computer simulation of the vehicle in which it will be mounted, through an appropriate combination of sensors and actuators. Cyber-physical benches enable the testing and validation of critical components before a full-system prototype is available. They allow multiple runs of different scenarios under controlled conditions, at a fraction of the cost of full-system prototype tests.

  The reliability of cyber-physical tests depends on the accuracy of the co-simulation interface, which explicitly couples physical and virtual components. Inaccuracies in the co-simulation interface can lead to unrealistic dynamics predictions, as explicit schemes may alter the energy balance of the overall system. To ensure the correct execution of experiments, energy must be carefully controlled at the interface. Additionally, factors such as information transfer and the limitations of sensors and actuators must be considered to guarantee the success of cyber-physical tests.
