This paper proposes a new approach to multisensor data fusion, suggesting by considering information about the sensors’ different characteristics, aggregation of data acquired by individual sensors can be done more efficient. Same as the most effective sensors’ characteristics, especially in control systems, our focus is on sensors’ accuracy and frequency response. A rulebased fuzzy system is presented for fusion of raw data obtained from the sensors having complement characteristics in accuracy and bandwidth. Furthermore, a fuzzy predictor system is also suggested aiming to extremely high accuracy for highly sensitive applications. The great advantages of the proposed sensor fusion system are revealed on simulation results of a control system utilizing the fusion system for output estimation.
