摘　　要：针对发动机的怠速控制问题,按照基于零阶T-S模型的模糊控制算法,研制了一种怠速模糊控制器。在Xilinx Spartan II型FPGA上实现了该模糊控制器电路,验证了该算法的有效性;用SMIC 0.18μm工艺研制了模糊控制器芯片,芯片面积为1.99 mm2,功耗为8.7 mW,工作频率达30 MHz。以模糊控制器为核心的控制系统经在发动机上实车试验,功能正确,控制效果良好。A fuzzy logic controller for engine idle speed control was designed. The fuzzy logic control algorithm was based on zero-order T-S model. The fuzzy logic controller was implemented on a Xilinx Spartan II FPGA, and the effectiveness of the algorithm was verified. Implemented in SMIC＇s 0. 18μm process, the controller chip occupies an area of 1.99 mm^2 , and it has an operating frequency of 30 MHz while dissipating 8. 7 mW of power. Experimental result on a real engine indicated that control system with the fuzzy logic controller functioned properly and a good control effect was achieved.
