A controller for controlling self excited oscillations in a combustion system. The controller comprises a phase lead compensator, and a Smith controller. The controller has the form: (I) V is the output voltage from the controller which will be used to drive the actuator, D is the input signal to the controller used to detect conditions in the combustor, S is a data vector of length N+2, K is the control parameter vector of length N+2, F is a filtered version of S, Vz is a filtered version of V, a and zc are positive constants, tau is the time delay between V and D, dt is the logging period, N= tau /dt and k1, k2, zc and lambda are constants. |
