Optimization of PID Based Temperature Control System for Wind Turbine Gearbox Based on Adaptive Particle Swarm Optimization Algorithm
In order to ensure the temperature stability of wind turbine gearbox,a temperature control system of wind turbine gearbox based on adaptive particle swarm optimization PID is designed.In this system,the temperature trans-mitter is used to obtain the real-time temperature data of the current wind turbine gearbox,and the real-time temper-ature data is input into the variable universe fuzzy PID controller through the analog input and output module for fuzzification,so as to divide the fuzzy space of the scale variable of the temperature control quantity,establish the control variable universe,and obtain the temperature control quantity of the wind turbine gearbox output by the PID controller according to the PID fuzzy rules.The experimental results show that the system has good operation stabili-ty,can quickly control the temperature of the gearbox of the wind turbine to a specified value,and has small over-shoot and excellent system performance.
