Decoupling control for the speed synchronization task in the powertrain of a hybrid electric vehicle

In this paper a novel framework for a multivariable control design task in the field of hybrid electric vehicles is introduced. The problem under consideration consists of a speed synchronization task of two propulsion aggregates using a controllable separation clutch. During this synchronization period the longitudinal vehicle motion of the vehicle should not be affected. The proposed control strategy is based on a decoupling network and two optimized controllers. The performance and robustness properties of the closed-loop system are shown by nonlinear simulation results.
