The paper presents a mechatronic hydraulic system with an adaptive regulator designed for a manipulator drive of mobile working machines. Manipulator has the following basic characteristics: a carrying capacity of up to 500 kg, a maximum boom length of 2.5 m, a lifting height of up to 2.8 m, a pump capacity of 16 kW, and rated pressure in the hydraulic system of 16 MPa. The mechatronic hydraulic system is built on a controlled pump, proportional hydraulic valves with electrohydraulic control, and a controller. The controller acts as an adaptive regulator and allows adjusting the feedback signal of the hydraulic system when changing its operating modes to improve its dynamic characteristics. A nonlinear model of the hydraulic system has been developed. Simulation studies of dynamic processes have been conducted. The possibility of reducing overregulation and oscillation in the hydraulic system has been found. An increase in operating speed has also been considered by introducing the corrective component of the feedback signal and its delay. A fuzzy inference system has been applied to model the dependence of the coefficient of the corrective component of the feedback signal.
