Hi,

since the topic of distributed control systems is a broad filed for study, maybe some of the papers could help you:

Hemeida, A.M.; El-Sadek, M.Z.; Younies, S.A., "Distributed control system approach for a unified power system," Universities Power Engineering Conference, 2004. UPEC 2004. 39th International , vol.1, no., pp.304,307 Vol. 1, 8-8 Sept. 2004

Addel-Geliel, M.; Khalil, A., "Adaptive fuzzy controller for loop control in a Distributed Control system," Control and Automation, 2009. MED '09. 17th Mediterranean Conference on , vol., no., pp.55,60, 24-26 June 2009

Liu Huai; Zhang Zheng; Huang Jianxin; Feng Chunmei, "Optimal scheduling algorithm for periodic tasks in distributed control systems based on PSO," Control and Decision Conference (CCDC), 2011 Chinese , vol., no., pp.2853,2857, 23-25 May 2011

Vogel-Heuser, B.; Biermann, C., "Requirements of a process control description language for distributed control systems (DCS) in process industry," IECON 02 [Industrial Electronics Society, IEEE 2002 28th Annual Conference of the] , vol.3, no., pp.2272,2277 vol.3, 5-8 Nov. 2002

and so on... Maybe you could specify your interests 

Dear, 

You may write on model order reduction using soft computing in process control systems. 

That is what I am trying to do right now, trying to find what interests me. Thank you for helping.
