Neural Network Based Adaptive Backstepping Control for Electro-Hydraulic Servo System Position Tracking

International Journal of Aerospace Engineering, 2022
The modeling uncertainties and external disturbances of electro-hydraulic servo system (EHSS) deteriorate the system’s trajectory tracking performance. To cope with this issue, an adaptive backstepping controller based on neural network (NN) is proposed ...
