Generalized Adaptation of an Electric-Hydraulic hybrid drive system
James Long Steve Edgeman , Xin Wang
KersTech Vehicle Systems is in the process of creating a hybrid drive system combining a flat format hydraulic motor with an electric motor for energy recapture of vehicle momentum. The initial drive system is targeted at a specific vehicle application. A main component of the drive system being developed is a controller and the associated algorithm. The controller algorithm is a new adaptation of an optimally robust algorithm for model uncertainties and resilience against control feedback gain…
