A New Intelligent Fuzzy Controller for Nonlinear Hysteretic Electronic Throttle in Modern Intelligent Automobiles

In order to control the nonlinear hysteretic electronic throttle adopted in modern automobiles, a new result for the tracking control of nonlinear hysteretic system is first proposed in this paper. Therefore we can realize the intelligent fuzzy logic controller in a well-behaved and systematic manner. A new closed-loop Back-propagation tuning is also proposed for the tuning of the fuzzy output membership functions to yield better tracking result. Finally, the controller synthesis is performed in a real-time environment using dSpace MicroAutobox and advanced microcontroller development board to yield excellent tracking results with cost-effective implementation.
