Robust tracking control of shape memory alloy (SMA) systems is a challenge because of their highly non-linear response, non-local memory and lack of differentiability. In this work, a linear parameter-varying (LPV) control method is proposed to compensate for the hysteretic behaviour of an SMA actuator. To provide information on the scheduling variable, the Preisach model of hysteresis is utilised...
This paper presents results of multimodal vibration suppression of a smart flexible cantilever beam by using single piezoceramic actuator and a single sensor. Piezoceramics PZT (lead zirconate titanate) patches are surface-bonded on the beam and perform as actuator and sensor. System identification for the dynamics of the first three modes and model reduction techniques are employed to assist in control...
