摘　　要：针对离合器位置跟踪问题,提出了一种专家PID控制算法,设计了专家调整策略,在不采用速度环的情况下实现了目标位置的准确跟踪。针对离合器接合规律问题,采用模糊控制和规则协调控制相结合的控制策略,以实现发动机恒转速起步。试验结果表明:专家PID控制算法具有较好的鲁棒性和控制精度,能够适应离合器位置跟踪控制要求;在不同工况下车辆均能顺利起步,且能够体现驾驶员意图。Aimed at problem of position tracking control of clutch, a new expert PID control algorithm was proposed, and expert adjustable strategy was designed. The PID control parameter was adjusted by expert experiment to implemented accurate position tracking control without speed control loop. Aimed at problem of engaging rule of clutch, a compound strategy combining fuzzy control and rule coordinating control was proposed to implement engine constant speed during starting. The experimental result shows that the expert PID control algorithm has better control accuracy and robustness and it can meet position tracking control command of clutch. The starting experiments show that vehicle can start successfully under various conditions and can reflect driver＇s intention.
