Includes bibliographical references (pages 113-114). A new approach for analyzing multiple control systems within the STPA framework has been developed and demonstrated. The new approach meets the growing need of system engineers to analyze integrated control systems, that may or may not have been developed in a coordinated manner, and assess them for safety and performance. This need comes from the increasing proliferation of embedded control systems across domains including defense, energy, healthcare, automotive, aerospace, and consumer products. When multiple embedded control systems are integrated together, they have the potential to operate in uncoordinated and conflicting ways which might hinder their performance and lead to unsafe behavior. This new approach provides a means for engineers to analyze the integration of control systems, beginning during concept development and continuing through the design process. The approach leverages the results of STPA Step 1 and guides the analyst in identifying instances of potential conflict between controllers. The method is demonstrated through a case study from the automotive domain, the integration of three driver assistance systems. The first application of the new approach identified instances of conflict amongst the three systems that would prohibit their successful operation in the field. Following the presentation of the case study, suggestions for future work and use in practice are provided. by Matthew Seth Placke.
