Desenvolvimento prático e simulação de estratégias de controle para electronic throttle control com variação no sinal de entrada

Abstract

This research presents a practical and theoretical approach of control strategies applicable in Electronic Throttle Control with changing of the input signal. Electronic Throttle Control is an automotive technology for acceleration systems, where occurs air intake to the engine according to the accelerator pedal position, using electronic systems and components. This project presents the system behavior in open loop, the development of a PID compensator for controlling the valve and the practical experiment of a controller developed in Arduino platform. All the configurations have been tested with signals such as sine wave, triangle, square and sawtooth with perform analysis. The results showed that the ETC with PID control performs a good response by many types of input and satisfies the requirements demanded by this application. It is also possible to conclude that, despite the system in Arduino to be suitable for academic studies, it does not present a good level of reliability and setting time for commercial purpose.
