摘要
用直流电机产生的气流来控制竖直管道中的小球位置是一个非常复杂的控制过程,具有非线性、时变性等特点。利用SolidWorks进行风罩的仿真设计,搭建风洞控制系统。将常规PID控制与模糊控制相结合,模拟人为控制经验,进行参数优化,达到理想的控制效果。在MATLAB中建立了系统控制模型,进行仿真实验。结果表明模糊PID控制可大大提高系统的动态性能。
With characteristics such as non-linearity and time-varying,controlling the position of the small ball in the vertical pipeline with the air current generated by the DC motor is a very complicated process.SolidWorks is utilized to simulate the wind hood and build a wind tunnel control system.This paper combines the conventional PID control with fuzzy control to simulate the artificial control experience and optimize the parameters to achieve the ideal control effect.A system control model is established in MATLAB for simulated experiment,and the results show that fuzzy PID control can greatly improve the dynamic performance of the system.
