abstract

• This paper presents an implementation of active control of thermoacoustic instabilities for a swirl-stabilized spray combustor. Loudspeakers located upstream of the burner were used as control actuators in the closed-loop system. Experimental models of the combustor dynamics were dev eloped using a non-parametric identification method. Several controllers were obtained based on optimal control strategies. These controllers were simulated and tested in the experimental setup showing good agreement. Phase-delay control w as used as a baseline method to compare the performance of these different controllers. The advantages of the model-based controllers over the baseline strategy are clearly presented. Copyright © 2001 by ASME.
