Model based development of engine control algorithms
conference paper
Model based development of engine control systems has several advantages. The development time and costs are strongly reduced because much of the development and optimization work is carried out by simulating both engine and control system. After optimizing the control algorithm it can be executed by a real-time control system which is hooked up to the engine. The real-time control system is also able to simulate the engine model in real time. This opens the way for Hardware In the Loop Testing of existing engine controllers, sensors and actuators. For the optimization of the closed loop control system for a Variable Geometry Turbocharger (VGT), fitted on a Heavy Duty (HD) diesel engine, simulated time responses as well as Nyquist diagrams were used. An improvement in transient engine behaviour was demonstrated, both with simulations and with measured responses on a transient test bench.
