Iterative Smooth Variable Structure Filter for Parameter Estimation
International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011 The smooth variable structure filter (SVSF) is a recently proposed predictor‐corrector filter for state and parameter estimation. The SVSF is based on the sliding mode control concept. It defines a hyperplane in terms of the state trajectory and then applies a discontinuous corrective action that forces the estimate to go back and forth across that ...
