Control design of Space Station Mobile Transporter with multiple constraints
Abstract
The dynamic analyses and controller design approach for the Mobile Transporter (MT) of Space Station Freedom are described, and the methodology used to design an optimum control system is outlined. It is shown that consideration of the structural flexibilities of the MT is essential to the control design. An unsatisfactory controller design results from modeling the MT as a rigid body. Despite the time variant structural characteristics of the MT during its motion, and adaptive controller design, which responds to structural changes by varying its gains in real-time, is not required. Controller gains must be changed prior to any motion to adapt the controller to its payload condition.
