In this work methods are presented to reduce driveline oscillations and preserve high performance during load changes for conventional, parallel hybrid electrified, and battery electrified powertrains. The methods address the dominant dynamics of backlash and time delay in the powertrain. Differentially flatness is used to invert the driveline system. Time delay compensation methods are formulated and compared with regard to stability and damping behavior using stability diagrams. The most promising compensation approach is combined with the nonlinear flatness-based feedforward control strategy to control powertrains with backlash and time delay.
