Fuzzy control in diesel working adjustment for HEV bus

In order to adjust the working of the engine for a full hybrid bus, fuzzy control was introduced in this paper to regulate the speed and torque of the diesel. In speed adjustment process, the rate of change was optimized and limited with fuzzy rules to avoid rapid and frequent change along with power required by the driver. Allow for complex engine model, fuzzy control method was introduced to regulate the torque response rate with PI regulator. Vast statistic data and experimental results verify the feasibility and effectiveness of the proposed control method in this paper. The busses in route have good fuel economy compared to the counterparts.
