International Journal of Control Science and Engineering

International Journal of Control Science and Engineering seeks to provide an outlet for technical papers on advances in the field of control systems and control technology. It aims at speedy, online publication of original, peer-reviewed papers in all established and newly emerging areas of control theory and applications, encompassing modeling, identification, estimation, analysis, design, implementation of control systems, and in broader and related areas of signal processing and systems and information sciences. The Journal employs a paperless, electronic submission and evaluation system to promote a rapid turnaround in the peer review process.
