B-Spline Approximation Using an EKF for Signal Reconstruction of Nonlinear Multifunctional Sensors.
IEEE Transactions on Instrumentation and Measurement（2011）
摘要
In this paper, a novel method based on a B-spline approximation and the extended Kalman filter (EKF) is proposed for the signal reconstruction of nonlinear multifunctional sensors. The B-spline approximation is a very effective and conventional tool for nonlinear modeling. However, the computation of the B-spline control array by the least square method is very complex for implementation on microp...
