Abstract:Networked control system (NCS) for industry process control recently has been paid much attention to. A fact that there exists networked-induced time delay in NCS, and the traditional proportional integral derivative (PID) controllers are still used broadly in industrial sites as their strong adaptability and robustness is well known. Therefore, the control engineers must face an unavoidable problem how to modify PID controller available for the networked-induced time delay in NCS. In this paper, the PID type of internal model control (IMC-PID) is suggested to handle the networked-induced time delay in NCS, where the internal model PID control is combined with PSO to find optimal proportional factor added to the deduced proportional gain, and OS-ELM to adjust the filter factor online. Simulations using Truetime blocks in Simulink/Matlab for the first and second order plants are given, and it is observed that the closed loop system has a well dynamics and adaptive performance. ? 2014 ICIC International.
