Abstract

Abstract: Through the improvement of small excavator hydraulic system, by using AMESim software and establishing a simulation model of excavator boom hydraulic system, the influence of PID controller parameters on the system dynamic performance was analyzed. At the same time, its dynamic performance was simulated and analyzed. The results show that the global optimal solution of PID parameters improves the performance of excavator boom hydraulic system and obtains good effect, which offers references for the frequency response speed and stability of the system.
