Identification and Control for Future Restraint Systems

摘要

In this paper, an approach to design an ideal restraint system is discussed. The problem, normally solved by optimization approaches, is translated to a tracking problem, where a given reference trajectory has to be tracked. Before a controller can be designed, identification of the local dynamic input-output behavior is performed in several operating points using stepwise perturbations added to the input. Using the obtained model, a stabilizing controller is designed with loop shaping for performance. Results are shown for the design of the belt force, such that the maximum chest deceleration of the driver in a frontal crash test with 56 km/h crash velocity, is minimized. A reduction of 60% of the maximum chest acceleration is achieved.
