Original Kurzfassung:
Dynamical test benches are typically used in the development phase of
engine systems and require tracking controllers with high performance.
Unfortunately, during such a work the components or operation parameters
of the engine system are changed very frequently, making the use of
classical model based control approaches very time-consuming. Against
this background, this paper proposes a direct data-driven design
approach for multivariable control of rotational speed and shaft torque
of an internal combustion engine at a test bench based on an extended
version of a recently introduced method for non-iterative direct
datadriven tuning of multivariable controllers. This extension allows
employing data collected in a closed-loop experiment in the direct
identification of the controller parameters. The effectiveness of the
proposed approach is shown on a test bench equipped with a production
light duty Diesel engine. A comparison with the industrial
state-of-the-art controller is provided on both a dynamically
challenging test and a typical driving cycle as measured on an
instrumented vehicle with the same internal combustion engine. The
results confirm that the new method recovers the performance of the
well-tuned industrial control, but can be developed in a fraction of the
time as no explicit model of the system is needed.
