Abstract
During experiments carried out in the fume hood, the fluidity and viscosity of the air in the fume hood cause problems such as turbulence and gas viscosity, which affect the accuracy of wind speed measurement on the fume hood. As a solution to these problems, an adaptive control system of wind speed on the fume hood based on the Kalman filter is designed. The improved Kalman filter is used to reduce the influence of turbulence and gas viscosity on the measurement of cover wind speed, and improve the measurement accuracy. The adaptive PID control algorithm is used to adjust the air valve to improve the control accuracy of cover wind speed. Experiments revealed that our proposed system for hood control outperforms traditional alternatives: it can effectively improve the measurement accuracy and control accuracy of the cover wind speed, reduce the number of control times of the air valve, improve the service life of the fume hood, and ensure the safety of experimenters.
