Abstract :
This paper deals with the estimation of force in a piezoelectric cantilever. The nonlinearities, i.e. hysteresis and creep, are taken into account. A nonlinear model relating the force, the voltage and the resultant deflection is first developed. The proposed estimator has been experimented and compared with the classical linear estimator. The results confirm the interest of the proposed method in term of accuracy.
