Abstract—This paper presents a description and analysis for the control circuit of noise in automobiles in the presence of diesel particulate filter( DPF), this paper aims to construct a control system for controlling the noise of the automobiles produced by the engine and then calculating the transfer function, T(s), that relates the output percent of noise to the input variables that can be represented by the magnitude and shape of tune of the engine sound. Analytical methodology is used here to formulate the transfer function and analyze the system. The response of the control system was calculated by taking the inverse of Laplace function of Y(s), it is found that the magnitude of the noise is attenuated and has a steady state response with some presented error that is directly depended on the specifications of the DPF such as its dimensions and porosity.
Index Terms—Control systems, diesel particulate filters noise control, transmission losses.
