Network based robust adaptive thermal control design for aluminum plate

In this paper, the main purpose is to stabilize the system with network delay and to achieve satisfactory output following performance. One of the most important problems is the time delay in networked control system (NCS). Firstly, the time-delay is approximated by Pade Approximation. Secondly, by using robust parallel compensator (RPC), an augmented process satisfying almost strictly positive real (ASPR) condition is obtained and adaptive output following control based on command generator tracker (CGT) method is proposed. Finally, network based robust adaptive temperature control for an aluminum plate thermal process is realized by using the proposed design scheme, and the effectiveness of that is confirmed.
