Chapter 19 - Adaptive Estimation and Control of Magneto-Rheological Damper for Semi-Active Suspensions

Abstract

Chapter 19 proposes adaptive parameter estimation and control for semi-active vehicle suspension systems with magneto-rheological (MR) damper. A hyperbolic model is first used to describe the non-smooth hysteresis non-linearity of MR damper, and then a new adaptive parameter estimation scheme is studied. Moreover, an adaptive control is designed to achieve vehicle suspension with MR dampers, where parameter estimation and control convergence can be retained simultaneously. The suspension performance requirements are also studied. Simulation results are given to illustrate the efficacy of the proposed method.
