A Traial of Precise Speed Estimation by Redundant Information Processing

A Traial of Precise Speed Estimation by Redundant Information Processing Gang-Hyeon CHOI*, Hideo NAKAMURA* and Hisato KOBAYASHI* 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.
