ELECTRONIC THROTTLE CONTROL

Electronic Throttle Control(ETC) is becoming an important part of
automotive industry. ETC or "Drive-by-Wire" system, if applied properly, can result
in an efficient control of throttle body. Position of the throttle body was the main
focus of the project. For this purpose RC servo motor for positional control was
used. The system was analyzed and a mathematical equation was derived. To
improve the system dynamics PID(Proportional Integral Derivative) control method
was applied using Matlab Simulink. Initially, the system was simulated and some
overshoot was detected which then was reduced using PID control. From the results,
it was observed that the integral par of the PID control does not or have very little
effect to the system, therefore the system was tuned using PD(Proportional Derivate).
In conclusion, a mathematical equation of the system was derived, simulated and
improved using PID successfully.
