Checking The Suspension Movements Considering The Flexibility Of The Vehicle Structure 931695

This work presents preliminary results from a research about active suspension control regarding vehicle body flexibility. At first we are examining the use of LQG-LTR method, which allows to consider unstructured uncertanties in the compensator design if the model has the same number of inputs and outputs. The method used makes an inverse of the plant, so it must not have transmission zeros with positive real parts. These requirements create some difficulties, leading to observability problems (probably) in the particular system used in the numerical analisys.
