| 摘 要： | 分析设计了已经被博世、电装、德尔福等公司量产化的模糊PID控制器,增加了模糊化前馈控制环节,给出了优化的控制策略和实现方法。通过对PID参数的在线自适应整定,实现了在不同柴油机工况下对共轨压力稳定性响应性的最佳控制。仿真结果和台架实验结果表明:模糊化前馈控制环节的引入可以显著提高瞬态工况下轨压的响应性及鲁棒性,并且不对稳态工况时轨压的稳定性产生负面影响。

| Abstract: | The paper analyzes and designs fuzzy PID controller already mass produced by Bosch, Nippondenso Co., Ltd., Delphy and so on. It adds fuzzy feedforward control and suggests optimized controlling strategies and method to realize. By on-line self-adjusting to PID parameters, the optimum control to common rail pressure stability and responsiveness is realized in different diesel conditions. The simulation result and bench test result show that the introduction of fuzzy feedforward control can greatly improve responsiveness and robustness of rail pressure in transient condition and not affect negatively stability of rail pressure in steady state condition. |
