【Abstract】 Aiming at the oil temperature control problem of high-pressure oil pump test circuit, this paper builds a tem-perature control system with the mixing valve as the core, and derives and establishes a mathematical model of the tem-perature control system. The PID algorithm and fuzzy control technology are combined to design the control algorithm, and MATLAB/Simulink is used to simulate and verify the temperature controller. The temperature control system of the high-pressure oil pump test bench is developed and a series of temperature control actual working condition experiments are carried out, and the PID parameters are adjusted online, and the analysis of the experimental results show that the temper-ature control system had high precision and rapid response ability.更多还原
