Abstract: The traditional load-sensitive technology used hydraulic lines to transmit pressure signals, and the stability and response speed of the system were reduced when dealing with fluctuating external loads and complex working conditions with frequent changes. In order to solve the problem, a fuzzy control servo pump-controlled electro-hydraulic load-sensitive system was proposed. First, the fuzzy servo pump-controlled electro-hydraulic load-sensitive system was established in comparison with the traditional multi-actuator load-sensitive system, and the control principle was elaborated. Then, the mathematical model of the system was established according to the control principle, and the fuzzy PID pressure controller was designed to improve the control accuracy of the system. After that, the AMESim-MATLAB joint simulation model of the system under multi-actuator and multi-load conditions was established, and the pressure control characteristics of the system were studied and compared with the control system under traditional PID controller. Finally, a servo-pump-controlled electro-hydraulic load-sensitive test platform was built, and the test results were compared with the simulation results to draw a conclusion. The research results show that the established fuzzy control servo pump-controlled load-sensitive control system has excellent pressure control effect, and the designed fuzzy PID controller has higher control accuracy and better dynamic response characteristics compared with the traditional PID controller.
