Cloud-Based Control Systems: Basics and beyond

Using advanced information technologies (IT) and Internet of things (IOT) methodologies, cloud-based control systems (CCS) emerge as natural paradigm of networked control systems (NCS) and it being under development by enforcing the concept of control as a service (CaaS). Day by day NCS methods strongly promoted for distributed closed-loop control and industrial automation systems and extremely developed to study the influence of bidirectional communication constraints. In this paper, we examine the basics of cloud-based control systems (CCS) where the controller methods and algorithms are remotely placed in cloud far from the physical system. This creates a two parts: cyber part and physical part. There are several issues arose including networking delays, data dropouts and vulnerability to attacks. Research activities into these and related directions are discussed.
