Abstract :
This paper compares two nonlinear observers designed to estimate a road condition parameter. Both schemes assume only wheel angular velocity is measured and are based on a quarter vehicle model. A stability analysis is made of the estimation scheme in the presence of noise associated with the wheel angular velocity measurement in an effort to explain the results from the simulations.
