  3. Abstract:
  4. In this paper, an approach to the synthesis of optimal preview control laws for active vehicle suspension has been studied. A basic three-dimensional, seven-degree of freedom car riding model, subjected to two road inputs, is considered. To obtain an enhanced control scheme, the input senses and measures road irregularities, using the contactless sensors fixed on the vehicle front bumper. The suspension systems are optimized, with respect to ride comfort, road holding and suspension rattle space. The performance of active, active and delay and active and preview, are compared with a passive system by numerical simulation in the time domain. The results show that optimal preview control improves all aspects of system performance simultaneously, including acceleration of the vehicle, tire deflection and suspension rattle space, with less energy required to obtain that performance
