Stability analysis of an active electromagnetic actuating suspension system

Öz

For Vehicle suspension systems, needs for high force density and ease of design made hydraulic actuating systems commercially viable but inefficient, with bandwidth requirement very small. With active electromagnetic suspension system, the lapse of providing adequate bandwidth is compensated. The governing differential equations of displacement interactions in both spatial and time domains were used and CEFLT algorithms employed in the stability analysis. An optimum for reduction of the electromagnetic actuating force acts as trade-off for given vehicle-road terrain parameters. System instability occurs when the value is decreased and stability is maintained when increased.
