DOI: 10.1109/access.2020.3033845
Abstract: In this article, a novel feedforward control method is proposed to control the hysteretic nonlinearity and resonance in piezoelectric-driven mechanism. A third-order rate-dependent Rayleigh model is established according to voltage dependence and rate dependence tests… read more here.
