Research on control strategy of handling stability for formula SAE (FSAE) pure electric racing car

摘要

This paper studies the control strategy of handling stability using an FSAE distributed drive pure electric racing car and the direct yaw moment control. The proportional integral derivative (PID) controller, fuzzy logic controller, and the PID and fuzzy logic joint controller of the additional yaw moment decision models are also designed. Under the double lane change condition, the designed control strategies are simulated and compared. The results show that compared with no control and PID control alone, the proposed PID and fuzzy logic joint control strategy can significantly reduce the steady-state value and the extreme value of the yaw rate by 43.87% at most, and those of the side slip angle by 68.53% at most. The convergence rates of the two have increased, improving the handling stability of the vehicle.
