Accuracy improvement of dynamic sensors using higher order sliding mode observers

In this paper, a dynamic sensor accuracy is improved by reconstructing the true sensor input signal from the dynamically distorted measurement corrupted by exogenous signals using higher order sliding mode observers (HOSMO). The proposed technique is used to estimate the true sensor signal thereby improving the transient response and driving the steady state error to zero in finite time. A case study on reconstructing an input of the planar metal-polymer composite sensor illustrates the efficiency of the proposed techniques.
