Precisive parking design of urban rail transit based on PSO-PID model
With the rapid development of urban rail transit in China,fully automatic has become an important development direction in this field.As one of the important indicators to measure the performance of fully automatic driving,the importance of precise parking technology has become increasingly prominent.To further explore and improve the accurate stopping ability of trains,this article establishes a train operation simulation environment based on the train dynamics model and SIMULINK module in MATLAB simulation software to obtain and analyze the train operation simulation curve,and to establish two different control simulation models based on PID control and PSO-PID control for comparative analysis.The experimental results show that compared with the traditional PID control method,PSO-PID control could optimize the parking accuracy from 1.02m to 0.26m.This significant improvement has fully proved that PSO-PID control could improve the parking accuracy of trains more effectively.
