Abstract
In this paper, definitions of degree of controllability/observability, which are defined based on a scalar value dependent on the controllab ility/observability Grammian matrix, are presented for discrete-time s ystems. The concepts of degree of controllability/observability are ap plied to the actuator/sensor placement problem for thin flexible orbit ing square platforms, The LQG transient time responses for several typ ical systems with different degrees of controllability and observabili ty are also displayed.
