Motor speed estimation by redundant processing

This paper tries to improve estimations of angle velocity of servo systems. Angle velocity is usually carried out from angle data by observers, numerical differentiation, f/v transformation and so on. In this paper, we merge the all data derived by the above all methods, and we try to derive the best estimation. The experimental results show that this merging method remarkably improves the estimations comparing with ones by using each method separately. This merging method may be used in another measurement problem and it may be generalized as a sensor software fusion technique.
