One of the first questions facing the designer of the control system for a large space structure is how many components¿actuators and sensors¿to specify and where to locate them on the structure. This paper presents a methodology which is intended to assist the designer in this process with respect to actuators. A measure of controllability is defined which is a quantitative indication of how well the system can be controlled with a given set of actuators. Then the effect of component unreliability is introduced by computing the average expected Degree of Controllability over the operating lifetime of the system accounting for the likelihood of various combinations of component failures. The problem of component location is resolved by optimizing this performance measure over the admissible set of actuator locations. The variation of this optimized performance measure with number of actuators is helpful in deciding how many components to use.
