LQR and PID Design Technique for an Electric Furnace Temperature Control System

摘要

This paper presents a Linear Quadratic Regulator Controller design for Temperature Control of an Electric Furnace System using MATLAB. Also, Proportional-Integral-Derivative (PID) Controller is designed for control of an Electric Furnace. The three PID parameters K_p, K_i, and K_d are obtained using two tuning methods, Ziegler Nicholas and Tyreus Luyben. Performance of the system using LQR and PID (using Ziegler Nicholas and Tyreus Luyben) control techniques for an Electric Furnace Temperature System is compared by analyzing the Time Response of the system. The result of simulation shows that LQR technique gives better performance for the given system.
