A system for controlling combustion dynamics is provided. The system includes a combustor having a combustion chamber and an inlet for feeding a fuel-air mixture into the combustion chamber. The system also includes a dome plate at an upstream end of the combustion chamber. The system further includes a liner along a length of the combustion chamber. The system also includes an actuator configured to control one or more recirculating zones in the combustion chamber.
