Control strategy for hybrid tracked vehicles using fuzzy logic
摘要
To solve the problem of power distribution for hybrid tracked vehicles (HTV), a supervisory control strategy is proposed. Firstly, power system integration is analyzed and modeled. Then the control algorithm is given. Two fuzzy logics are used to realize the coordination control over each power unit. One controls power distribution based on the load power and battery state of charge (SOC). The other manage the power during regenerating braking. To validate the presented control strategy, a driver and controller in the loop simulation platform is built based on dSPACE system and real-time simulation is made. The simulation results show that the strategy presented can solve the power distribution problem of hybrid tracked vehicles correctly and effectively.
