The performance of a powertrain is dependent on how its controller parameters are tuned for the given duty cycle. In real world, the duty cycle is hard to predict, however, if the historical performance is evaluated and used to fine tune the controller parameters, the performance of the powertrain can be improved. This paper presents a retrospective information-based powertrain performance improvement. The performance is evaluated using the fuel economy and charge sustaining operation of an electrified powertrain. A Retrospective Cost Adaptive Controller (RCAC) has been designed for parallel HEV, which improves it performance based on the former performance. The simulation results demonstrate that the controller parameters are re-calibrated to show improved performance for a given duty style.
