Abstract

Systems monitored using sensors MEMS (micro electro-mechanic systems), has been developed and used in many areas of engineering becoming increasingly common in applications in various sectors of industry. The application in the car segment as ABS system, traction control system, steering control, has reached to popular vehicles due to reduced cost and ease of implementation. However due to their constructive nature MEMS generally have poor accuracy and high internal noise. The use of multiple MEMS sensors is one of the solutions to this limitation being objective of this research plan. This technique associated with appropriate signal processing methods (redundancy, fusion, state observers, Kalman filter, etc.) improves their functional characteristics extending its functionality directly identifying the angular acceleration that is the goal of this project. The final product is of interest in various areas of engineering, including metro, railways and buses, diversifying and expanding its application range. A prototype will be built for a field-testing application in a railway train of CPTM. (AU)
