Summary:This paper presents the design of Linear Quadratic Regulator and Pole Placement controllers with integral action using MATLAB and Simulink for controlling the temperature field in the secondary cooling zone of a continuous casting process. The secondary cooling zone in continuous casting represents a distributed parameter system. During steel production, the type of steel produced changes continuously, necessitating a control system that can respond quickly and flexibly. We compared the performance of the Linear Quadratic Regulator and Pole Placement control techniques for the temperature field in the secondary cooling zone by analyzing the system's response. The simulation results demonstrate that the Linear Quadratic Regulator technique outperforms the Pole Placement technique for the specified system.
