Abstract EN
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 hyperplane.
The SVSF is robust and stable to modeling uncertainties making it suitable for fault detection application.
The discontinuous action of the SVSF results in a chattering effect that can be used to correct modeling errors and uncertainties in conjunction with adaptive strategies.
In this paper, the SVSF is complemented with a novel parameter estimation technique referred to as the iterative bi-section/shooting method (IBSS).
This combined strategy is used for estimating model parameters and states for systems in which only the model structure is known.
This combination improves the performance of the SVSF in terms of rate of convergence, robustness, and stability.
The benefits of the proposed estimation method are demonstrated by its application to an electrohydrostatic actuator.
