Optimal actuator/sensor placement for control of combustion instabilities

A methodology for determining the optimal actuator and sensor locations for the control of combustion instabilities is presented. The approach relies on the quantitative measures of the degree of controllability and component cost. These criteria are arrived at by considering the energies of system's inputs and outputs. This paper describes a systematic procedure that associates weights that reflect the importance of each state variable or mode in a given cost function, thus, increasing the system controllability and its overall performance.
