Abstract:

The dynamic response of a vehicle can be improved considerably by an active suspension, so it enjoys a growing popularity within urban cars. The vehicle vibrational modelstypically include many degrees of freedom, therefore the implementation of model-based feedback (feeding of statevariables) control strategies in active suspension involvesabundant measurements which lead to a big challenge. The observation technique is a conventional method employed toestimate the state variables and to reduce the number of output variables. As the number of measurements and correspondingsensors decrease, cost imposed to the system will decrease and the complexity of hardware implementation is also reduced. Thepurpose of this research is to investigate different outputconfigurations and to determine the optimal sensory layout to achieve an ideal observer. Finally, a case study consisting of afour state quarter car model and two types of traditional sensors (acceleration and relative displacement) has been conducted.The presented algorithm takes a set of pre-defined sensors as input and analyses its various combinations. For eachcombination which forms a specific arrangement of outputs, the design metric is calculated through simulating assembled model of vehicle-controller-observer. This metric is a weighted sum of measure variables norm like passenger acceleration and estimation error.
