Backstepping Control of Electro-Hydraulic Arm
2018 6th International Conference on Control Engineering & Information Technology (CEIT), 2018 In this study, positioning control of the electro hydraulic systems is considered. Backstepping control strategy is designed by defining an auxiliary error signal. The performance of the controller is investigated by conducting numerical simulations. From the simulation results, it is seen that the control objective achieved successfully.
