碩士 === 國立交通大學 === 電控工程研究所 === 100 === In this research, we focus on the design and implementation of idle speed control by using electronic throttle. We design the controller for the electronic throttle of Saab company, 91 88 186, which is driven by a DC brushless motor. Our experimental car is Saab 9000 CSE (1994). We use two boards, Duemilanove and Pro Mini from Arduino company with Optical Coupler for noise isolation and H-bridge for power booster up to 12V, 5 amp. In this paper, we use Fuzzy Theory to design a FLC (Fuzzy Logic Controller) and translate it to an Off-line FLC look-up table, which can manipulate electronic throttle to reach idle speed in reality. Other automobile applications will be the heavy turbo charger control, ventilation control for engine room, the APC (Automatic Pressure Control), or cruise control system.
