【Abstract】 Inappropriate choice of sensor output variables for a flexible manipulator can lead to the deterioration of performance of a mode estimator, even the reliability of the mode reconstruction. This paper presents the case studies on the multi sensor combination schemes needed for the modal state reconstruction via Kalman filter. The performance indices for evaluating the quality of the mode state reconstruction are established, the recognition of the inferior schemes of multi sensor combinations are explored for achieving the desired performance of Kalman filter design.更多还原
