Nonlinear Observer-Estimator Application: Quarter-Car Suspension System under Road Disturbances
The aim of this article is to present the application of a useful technique that allows to design a nonlinear observer capable to estimate an unknown dynamics in the system under analysis. In order to have a practical example, the controller design for a quarter-car suspension system under road perturbations is presented. The lack of exactitude for system parameters values and the necessity to identify the variables measurement makes this system ideal to apply the observer-identifier.
