Actuator and sensor selection for an active vehicle suspension aimed at robust performance

A recently presented method for actuator and sensor selection for linear control systems is applied and evaluated for an active vehicle suspension control problem. The aim is to eliminate the actuator/sensor combinations for which no controller exists that achieves a speci® ed level of robust performance. Complete controller synthesis is avoided by using necessary conditions for robust performance. Due to this, it cannot be guaranteed that a stabilizing and robustly performing controller exists for the combinations satisfying the conditions. This is a major shortcoming of the method. Depending on the application and implementation, the computation time consumed by the selection procedure can be large.
