The design of self-adaptive and autonomic software systems raises many challenges. In his PhD thesis, Russel Nzekwa [12] proposes a new result with the CORONA framework that enables to build flexible autonomic systems. CORONA relies on an architectural description language which reifies the structure of the control system architecture. CORONA enables the flexible integration of non-functional-properties during the design of autonomic systems. It also provides tools for checking conflicts in the architecture of autonomic systems. Finally, the traceability between the design and the runtime implementation is carried out through the code generation of skeletons from architectural descriptions of control systems. The work on CORONA goes toward the long term objective of setting up an integrated design and programming solution for self-adaptive systems, where feedback control loops play the central role as first class elements.
