SIMULATION STUDY ON A NOVEL METHOD OF CONTROLLING CO2 CONCENTRATION BY VARIABLE FRESH AIR VOLUME IN CARRIAGE
The main purpose of this study is to present a novel control strategy on controlling CO2 concentration in carriage by variable fresh air volume. Dynamic model of a typical carriage for ventilation is established. The performance of the novel strategy is investigated. Simulation based on MATLAB, which the novel control strategy is adopted, is carried out. In order to show that the novel control strategy outperform better than convention PID control, a comparison is made between the performance of conventional PID and the novel nonlinear feedback control strategy. The results show that nonlinear feedback control strategy outperforms better than conventional PID control system in celerity, stability and other aspects.
