“…In order to continuously improve the operation efficiency and operation quality of excavator, and to expand the application areas of the excavator, autonomous operation has become an important research direction [1,2]. A key problem of the excavator's autonomous operation is how to establish the scientific effective model of the electrohydraulic servo system and improve the trajectory tracking accuracy of the robotic excavator [3,4]. Due to the existence of dead zone, saturation, nonlinear friction, and the nonsymmetry of hydraulic cylinder, the electrohydraulic servo system has strong nonlinear and time-varying characteristics [5][6][7][8].…”

“…Feng et al 9 reported a predictive control strategy based on a random model, which improved fuel economy by 44.2–61.9%. In addition, Park et al 10 reported a control strategy utilizing online learning based on echo-state networks. Wu et al 11 proposed a dynamic programming control strategy applied to transportation machinery.…”

“…Busquets and Ivantysynova 17 put forward an adaptive control based on back stepping. In addition, Kalmari et al 18 and Park et al 19 studied several kinds of nonlinear model-based predictive control algorithm. The common feature of the aforementioned algorithm is that the system nonlinearity was considered and the nonlinear models were used.…”
