| Abstract: | A new evaluation measure is proposed in the paper to give reasonable assessment of modal controllability and observability for each mode. By making use of the relationship between the image and kernel spaces of Grammian matrices and the controllability and observability, a measure of modal controllability and observability is defined. Accordingly, the locations of actuators and sensors are then determined. An illustrative example is presented for verification. |
