Optimisation of Active Suspension Control Inputs for Improved Vehicle Ride Performance
Vehicle System Dynamics, Vol. 54, No. 7, pp. 1004-10302016A collocation-type control variable optimization method is used in the paper to analyze to which extent the fully active suspension (FAS) can improve the vehicle ride comfort while preserving the wheel holding ability. The method is first applied for a cosine-shaped bump road disturbance of different heights, and for both quarter-car and full 10 degree-of-freedom vehicle models. A nonlinear anti-wheel hop constraint is considered, and the influence of bump preview time period is analyzed. The analysis is then extended to the case of square- or cosine-shaped pothole with different lengths, and the quarter-car model. In this case, the cost function is extended with FAS energy consumption and wheel damage resilience costs. The FAS action is found to be such to provide a wheel hop over the pothole, in order to avoid or minimize the damage at the pothole trailing edge. In the case of long pothole, when the FAS cannot provide the wheel hop, the wheel is traveling over the pothole bottom and then hops over the pothole trailing edge. The numerical optimization results are accompanied by a simplified algebraic analysis. active suspension; ride comfort; optimisation; analysis; collocation method
