Simulation Research on Hydraulic Loading System of Wind Turbine Based on Particle Swarm PID Control

摘要

As the key part of the wind turbine transmission chain to bear the load of the wind turbine, the quality of its working characteristics directly affects the basis of important performance such as the safety, stability and reliability of the system. This paper studies the hydraulic loading system of wind turbines. The mathematical model of the valve-controlled hydraulic loading system was established and simulated in MATLAB. The PID control method and the fuzzy PID control method based on particle swarm algorithm are selected to model and simulate the closed-loop control system of the hydraulic loading system. Through comparison, it is concluded that the hydraulic loading system based on PSO PID control has the advantages of fast response speed and stable system.
