Abstract :
This work aims in evaluating the closed loop performance of reaching law based discrete time sliding mode controller with multisensor data fusion (MSDF). The work considers six different fusion algorithms, to measure and control the structural vibration of piezo actuated cantilever beam. The vibration is measured using two piezo homogeneous sensors. Each sensor output uses separate estimator, for generating the states, which are then fused. The linear dynamic model identified using linear Recursive Least Square (RLS) method based on ARX model is used to illustrate the effectiveness of closed loop performance with data fusion, as compared to the single sensor case.
