Stabilizing Fuzzy control for Vehicle Active Suspension : LMI approach

Active suspension, Fuzzy Model, Vehicle, LMI

In this paper, a stabilizing fuzzy controller desing for active vehicle suspension is studied. After giving the nonlinear model of the active suspension, its representation by a Takagi sugeno fuzzy model is discussed.The closed loop stability conditions of the vehicle with the fuzzy controller and the observer are parameterized in terms of Linear Matrix Inequalities (LMI) problem which can be solved very efficiently using convex optimization techniques. Simulations of nonlinear vehicle active suspension with two degrees of freedom are given to illustrate the result.
