Abstract
A rule-based fuzzy gain-scheduling proportional integral (PI) controller is provided to control desired engine power and speed behavior in a power-split HEV. The controller includes a fuzzy logic gain-scheduler and a modified PI controller that operates to improve on the control of engine power and speed in a power-split HEV versus using conventional PI control methods. The controller improves the engine power and speed behavior of a power-split HEV by eliminating overshoots, and by providing enhanced and uncompromised rise-time and settling-time.
