Sensor and Actuator Selection for Large Space Structure Control.
Abstract
This paper presents an algorithm which aids the controls engineer in specifying a sensor and actuator configuration for regulation of large scale, linear, stochastic systems such as a large space structure (LSS). The algorithm uses a linear quadratic gaussian (LQG) controller, an efficient weight selection technique based upon successive approximation, and a measure of sensor and actuator effectiveness to provide a final sensor and actuator configuration. This configuration enables the closed-loop system to meet output specifications with minimal input power. The algorithm involves no complex gradient calculations and has proven numerically tractable for large linear models. Additionally, the algorithm provides the controls engineer information on the important design issues of actuator sizing, reliability, redundancy, and optimal number.
