Abstract：In this paper,a mathematical model of an electro-hydraulic position servo system is established with reference to the data manual of the system,and the physical simulation is carried out by Matlab,which shows that the mathematical modeling is feasible.In addition,in order to solve the difficulty of adjusting the parameters of the PID controller in the electro-hydraulic posi-tion servo system and the shortcomings of the nonlinear and conventional control of the system,combined with the improved particle swarm algorithm proposed in this paper,the controller parameter self-tuning algorithm is designed,and the improved PSO algo-rithm and the conventional PSO algorithm are simulated in Matlab.Through the comparison of experimental results for many times,it is concluded that the PID controller parameter self-tuning based on the improved PSO algorithm is more superior to the static and dynamic control effects of the servo system,and the calculation speed is faster.
