| 摘 要： | 以LPG发动机的怠速控制为研究对象，提出了模糊智能积分PID复合控制方法，并将控制算法在80C196KC为主控制单元、TMS320C5402DSP为辅助计算单元的ECU上实现。在轿车单一LPG气态进气道顺序喷射发动机上进行了试验研究，试验结果表明该控制方法既具有较小的稳态偏差又具有较好的动态特性。

| Abstract: | A An intelligent-integration fuzzy PID control strategy is proposed for idle speed control of a LPG engine. The algorithm is implemented by the ECU, consisting of a main control unit 80C196KC and an auxiliary calculating unit TMS320C5402DSP. Experiment is conducted on a pure LPG port sequential injection engine of a passenger car. The results demonstrate that the control strategy has relatively little static errors with better step response characteristics. |
