Summary: This article presents an incremental linear model predictive control (ILMPC) scheme based on the global linearization prediction neural network (GLPNN) model to compensate nondispersed and dispersed hysteresis. The GLPNN model of PEA is investigated to capture hysteresis behavior over a wide frequency band. A specially designed data-driven neural network precisely identifies the model, with modeling error less than 10% of previous models. The real-time ILMPC scheme is proposed to achieve hysteresis compensation, which exhibits better tracking performance for PEAs over a wide nonresonant frequency band compared to existing compensation strategies.

Summary: This study investigates the cross-sectional deformation of piezoelectric cantilever-actuators considering both anticlastic and electromechanical bending effects. The Searle parameter is found to play a key role in characterizing the shape of the cross-section. A load scaling rule provides a criterion for fixed cross-section deflection for different actuator widths, maintaining the Searle parameter unchanged.
