Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2013 This paper presents the robust tracking control of EHA (Electro Hydrostatic Actuator) system. EHA system provides the simple structure and frees from the environment pollution, but the poor tracking performance is caused by the internal leakage, surging ...

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 ...
