A key element in the successful completion of the joint flight phase was the capability of the Shuttle to control and stabilize the large flexible mated Shuttle / Mir stack.  This was done to within tight loading constraints and moderate pointing requirements.  This paper provides an overview of the Shuttle control system, summarizes the pre-flight frequency domain design and time domain analysis process and presents the flight results from the STS-71 Shuttle / Mir mission.<br><br>
