Abstract
To control the sand/dust concentration effectively is a major difficulty of sand/dust environmental test tunnel's control system design. Based on the dynamical analysis, a mathematical model of sand/dust concentration change is built up, and a concentration control strategy, in which feeder speed and valve's open degree are adjusted at same time, is presented and simulated. Simulation results show that this control strategy can effectively improve the control effect of sand/dust concentration in helicopter's environmental test tunnel.
