The impact of uncertainty blocks on time delay systems is the main subject of this research, which explores the complex dynamics of data communication networks. Within the field of computer science, the research delves into the difficulties presented by uncertainty blocks in the context of time delays, with the goal of elucidating their effects on the general effectiveness and dependability of data transmission networks. To maintain competitiveness in the markets for auxiliary services (such frequency regulation and load following), a highly distributed and networked communication system must be developed. Robust controller architecture with several unknown time-varying delays is considered for flow control problems. While the major focus is on data-communication networks, other flow control problems can also be solved with the suggested approach, and it can even be extended to problems involving several unpredictable time delays. This paper presents a PD controller for Networked Control Systems (NCS) with delay. The primary causes of the issues with networked control systems (NCS) are delays in data transfer via the communication network. A comparative performance analysis for different network delays is carried out. In order to simulate an AC servo motor control system, this study uses the Controller Area Network (CAN-Bus) as the communication network medium. MATLAB True Time package is used in the simulation to investigate the effects of different delays. The results of this study advance the field of computer science by illuminating these crucial elements and deepening our understanding of the complex nature of time delay systems in data communication networks. They also offer insightful information for the creation of reliable and resilient communication protocols.
