Genetic Algorithm-Based Mach Number Control of Multi-Mode Wind Tunnel Flow Fields

There are unfavorable conditions such as constantly changing working and frequent disturbances that affect Mach number control in wind tunnel flow fields. As the proportional, integral differential (PID) parameters need to be re-tuned for each of a tunnel, operational costs tunnels very high. Therefore, lower these costs, genetic algorithm was utilized tune PID achieve multi-mode field. In this paper, firstly, models were established; secondly, system designed based on effects proposed verified by simulations compared with PSO tuning system.
