Control algorithm for emission test simulation


Automobiles are one of the main sources of global pollution. In order to prevent manufacturing of cars with high pollution, appropriate institutions are performing standard emission tests before the final product is released in the market. Recently, some robots and electronic devices are dedicated to perform such tests instead of human drivers. In this paper, simulation of the vehicle with the brake and the throttle as inputs, and the velocity, the position and the main components of exhaust gas as outputs in the emission test circumstances is discussed. The main components of exhaust gas are measured during the simulation. The performance of a nonlinear fuzzy controller and a conventional PID controller are compared to control the vehicle in such a test.
