摘　　要：介绍了怠速递阶模糊控制策略和发动机怠速状态的动态模型,针对怠速状态的内在不稳定性和怠速控制目标的多样性,提出了具体的控制方法,给出了实际应用结果。This article introduces in detail the strategy of idle speed hierarchical fuzzy control developed by the authors. At first, the dynamic model of engine in idle status is presented. In focus on the inherent instability of engine in idle status and the diversity of idle speed control, the specific control method is described in detail. Finally, practical application result is given.
