To enhance the control efficiency and precision of the proportional valve-controlled hydraulic cylinder,a method for optimizing fuzzy PID parameters using particle swarm optimization is proposed to address the issues of slow system response speed and low tracking accuracy.A combined AMESim-Simulink simulation platform is established,employing a fuzzy PID control algorithm based on particle swarm optimization for the proportional valve-controlled hydraulic cylinder system.The particle swarm algorithm is utilized to fine-tune the parameters of the fuzzy PID,and simulations are conducted using the AMESim-Simulink joint simulation platform.The simulation experiments validate that the particle swarm optimized fuzzy PID controller improves system response speed,reduces overshoot,and enhances stability in the proportional valve-controlled hydraulic cylinder system.
