Switching Stability of Automotive Roll Dynamics Subject to Interval Uncertainty
Solmaz, Selim and Shorten, Robert and Mason, Oliver (2008) Switching Stability of Automotive Roll Dynamics Subject to Interval Uncertainty. Proceedings in Applied Mathematics and Mechanics, 8 (1). pp. 10921-20933.
In this paper we apply some recent results on the stability of switched systems with interval uncertainty for analyzing the roll stability of automotive vehicles subject to bounded parametric uncertainties and switching. The application is motivated by the fact that the roll dynamics of an automotive vehicle is affected in a significant and a nonlinear fashion due to possible sudden switches in the vehicle’s center of gravity (CG) height, as well as the uncertainty in the suspension parameters. Utilizing a recent stability result, it is possible to model such parametric variations as bounded interval uncertainties for this problem, and obtain easily verifiable conditions for analyzing the stability of the resulting switched/uncertain system.
