Effect of Weight Number of Object Function on Control Force and Performance of Vehicle Active Suspension 2007-01-3572
The influences among the weight number of object function, maximum value of suspension optimum control force and suspension performance are analyzed in this paper. A total state feedback controller for the 7-degree-freedoms modal of total vehicle based on random optimum control strategy is built. By ADAMS &MATLAB \simulink co-simulation, the influence of weight number of object function on maximum value of suspension control force and suspension performance is discussed in the paper. It obtains the relations among maximum value of suspension optimum control force, suspension performance and the variety of weight number Then a set of weight number which are applied to the object function of optimum control for the car are selected at last. Under the action of co-simulation, the ride comfort and control stability of the car are obviously improved, and the maximum value of suspension optimum control force is satisfied with the engineering requirement when the preferred value of weight number is used.
