Abstract :
For intermittent wind tunnel, the Mach number in test section is difficult to control because of unpredictable changes in wind tunnel process dynamics and restriction of air storage volume. To cope with the problem, a synthetic approach which combines adaptive and auto-tuning with feedforward control strategy, is presented. The adaptive and auto-tuning controller with a recursive parameter estimation of a first-order or second-order model with delay, is employed to control the transient and the steady state for the Mach number in test section. The transient controller designed by the motion law method has an excellent performance of set point tracking and the steady state controller is of PID type whose parameters are tuned by the SPAM tuning for rejecting load disturbance. The feedforward controller is used to compensate the loss of air storage pressure. The experimental results demonstrate the effectiveness of the proposed controllers
