Neural Network Based Hysteresis Compensation of Piezoelectric Stack Actuator Driven Active Control of Helicopter Vibration

•A neural network based method for hysteresis modeling and compensation of Piezoelectric Stack Actuators (PSAs) when actuated by multi-harmonic signals has been presented in the manuscript.•The neural network based compensation method for PSA’s hysteresis integrated in the PSAs-driven active control system of multi-harmonic helicopter vibration has been presented in the manuscript. The experimental results by using the active vibration control system show the effectively improved vibration reduction performance comparing with no compensation.
