The Design and Simulation of Modified Imc-pid Controller Based on Pso and Os-elm in Networked Control System

چکیده
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.

A Unified IMC based PI/PID Controller Tuning Approach for Time Delay Processes
This paper proposes a new PI/PID controller tuning method within filtered Smith predictor (FSP) configuration in order to deal with various types of time delay processes including stable, unstable and integrating delay dominant and slow dynamic processes. The proposed PI/PID controller is designed based on the IMC principle and is tuned using a new constraint and without requiring any approxima...

Microgrids is an new opportunity to reduce the total costs of power generation and supply the energy demands through small-scale power plants such as wind sources, photo voltaic panels, battery banks, fuel cells, etc. Like any power system in micro grid (MG), an unexpected faults or load shifting leads to frequency oscillations. Hence, this paper employs an adaptive fuzzy P-PID controller for f...
