Model-Based Test Bench Conditioning Systems Control
Abstract Engine test benches are crucial instruments to perform tests on internal combustion engines. Possible purposes of these tests are detecting engine performance, checking the reliability of engine components or making a proper calibration of engine control systems managing the actuations. Since many factors affect tests results in terms of performance, emissions and components durability, an engine test bench is equipped with several conditioning systems (oil, water and air temperature, air humidity, etc.), in order to maintain the controlled variables to the target values, throughout the test duration. The conditioning systems are often independently controlled by means of dedicated Programmable Logic Controllers (PLC), but a centralized model-based management approach could offer several advantages in terms of promptness and accuracy.
