In this paper, optimal design of PID controllers has been proposed for time delay systems using various soft computing algorithms. Time delay systems exist in several real world applications, and the delay is generally caused by the time taken by the sensor to sense the parameter, communication delay etc. Hence such characteristics lead to instabilities and make it difficult to control the system...
Networked control systems (NCS) have gained an increasing attention in recent years due to their flexibility and cost reduction. The two main problems affecting stability and performance of closed-loop NCS are packet delay and drop. The problem of delay is severe in large scale NCS where the sensor-controller-actuator are connected via a network with large number of switches and routers. In this paper,...
