Abstract: In this paper, we overview the importance and design of robust feedback control in challenging application of Hybrid Electric Vehicle (HEV) energy management. The HEV dynamic is highly-coupled two-input two-output with severe interactions between internal combustion engine and electric motor. Moreover, it is subjected to parametric uncertainties (engine lag, rotational moment of inertia and damping), unmodelled dynamic (ignition/combustion delay) and unmeasurable exogenous disturbances (engine torque loss and clutch torque). We demonstrate that a robust multivariable design has great potential to provide guaranteed stability- and performance-robustness for this challenging application. Simulation results also verify the above leading towards reduced calibration cost and time.
