| Abstract: | Based on electromagnetic theory, electromagnet is used for actuator of active suspension and a general electromagnetic actuator is constructed. On the basis of one-fourth automobile suspension, a nonlinear model is built for electromagnetic active suspension and a sub-optimal controller is designed by applying modern control theory. By analyzing and simulating the model system, the result shows that electromagnetic active suspension can carry out the function of general active suspension, and can cater for the requirements of vehicle ride comfort. It can be applied on suspension system of automobiles. |
