Controlling Unstable Rolling Phenomena
The paper addresses dynamic and control issues related to a dynamical model called the classical shimmying wheel. The classical shimmying wheel models the rolling dynamics of many physical rolling systems such as aircraft nose wheels, motorcycles, automotive systems and tractor{ trailer systems. Such system can exhibit undesirable unstable rolling motion, i.e. shimmying, which can often lead to...
متن کاملControlling patterns of geospatial phenomena
Modeling spatially distributed phenomena in terms of its controlling factors is a recurring problem in geoscience. Most efforts concentrate on predicting the value of response variable in terms of controlling variables either through a physical model or a regression model. However, many geospatial systems comprises complex, nonlinear, and spatially non-uniform relationships, making it difficult...
متن کاملAnalysis and Control of Unstable Rolling Wheel Dynamics
Many vehicle systems contain rolling elements which exhibit unstable rolling motion, called shimmying, which may lead to disastrous results. The classical shimmying wheel is a simple model which captures the essential dynamics of such systems. In particular, the uncontrolled stability of the rolling wheel is characterized by a subcritical Hopf bifurcation when certain parameter values are varie...
متن کاملModelling Rerouting Phenomena through Dynamic Traffic Assignment in Rolling Horizon
This article addresses the problem of simulating en-route path choices on transport networks. In particular, by rerouting, we mean changing the currently chosen path, after receiving some information about a traffic event. Indeed, when the forecasted performance pattern of travel times and costs, known or only perceived, changes significantly, drivers may react by shifting their current route t...
متن کاملModeling Supply Networks and Business Cycles as Unstable Transport Phenomena
Physical concepts developed to describe instabilities in traffic flows can be generalized in a way that allows one to understand the wellknown instability of supply chains (the so-called “bullwhip effect”). That is, small variations in the consumption rate can cause large variations in the production rate of companies generating the requested product. Interestingly, the resulting oscillations h...
