INTERNET-BASED REAL-TIME CONTROL ARCHITECTURES WITH TIME-DELAY/PACKET-LOSS COMPENSATION Academic Article

abstract

• The main objective of this paper is to demonstrate the feasibility of Internet-based real-time control. A novel client/server-based architecture for Internet-based supervisory control with common gateway interface/hyper text markup language (CGI/HTML) interface is presented. A real-time operating environment was established for closed-loop control over Ethernet. We conceived of an autoregressive (AR) prediction scheme and a novel compensation algorithm to compensate for network-induced time delays and data-packet losses simultaneously. We constructed an open-loop unstable ball magnetic-levitation (maglev) setup as a test bed to validate the two proposed control architectures. Experimental results proved the feasibility of Internet-based real-time control and verified the effectiveness of the proposed time-delay/packet-loss compensation algorithm in networked feedback control systems.
