SENSOR AND ACTUATOR SELECTION FOR OPTIMAL CLOSED-LOOP PERFORMANCE IN THE PRESENCE OF CORRELATED NOISE. | Conference Paper individual record
abstract

A method is presented for the selection of sensors and actuators whose outputs may contain correlated noise. A generalization of the earlier results of closed-loop input-output cost analysis is provided which utilizes decompositions of the closed-loop quadratic cost function into contributions from each stochastic noise input and each weighted output. It is shown that under certain circumstances the elimination of a correlated noise input may degrade performance. Application to a flexible space structure demonstrates the generalized method for sensor and actuator selection.
