IET控制理論和應用廣泛應用于控制系統，涵蓋了新的理論成果和新的和已建立的控制方法的應用。感興趣的主題包括系統建模、識別與仿真、控制系統的分析與設計（包括計算機輔助設計）以及實際實施。范圍包括技術、經濟、生理（生物醫學）和其他系統，包括人機界面。大多數發表的論文都涉及工業和政府實驗室和大學的原著，但歡迎對現有方法進行主題回顧和導師講解。歡迎函電討論發表的論文。申請論文不必涉及新理論。描述對既定方法的新實現，或在新情況下應用的控制技術，或比較各種設計的實踐研究的論文將是有意義的。特別有價值的是討論產生新理論應用的新工作或應用的適用性的理論論文。

IET Control Theory and Applications is devoted to control systems in the broadest sense, covering new theoretical results and the applications of new and established control methods. Among the topics of interest are system modelling, identification and simulation, the analysis and design of control systems (including computer-aided design), and practical implementation. The scope encompasses technological, economic, physiological (biomedical) and other systems, including man-machine interfaces.Most of the papers published deal with original work from industrial and government laboratories and universities, but subject reviews and tutorial expositions of current methods are welcomed. Correspondence discussing published papers is also welcomed.Applications papers need not necessarily involve new theory. Papers which describe new realisations of established methods, or control techniques applied in a novel situation, or practical studies which compare various designs, would be of interest. Of particular value are theoretical papers which discuss the applicability of new work or applications which engender new theoretical applications.
