Abstract
Electric furnaces play an important role in many industrial processes where precise temperature control is essential to ensure production efficiency and product quality. Traditional proportional-integral-derivative (PID) controllers and their modified versions are commonly used to maintain temperature stability by reacting quickly to deviations. In this study, the real PID plus second-order derivative (RPIDD 2 ) controller is introduced for the first time for industrial temperature control applications, which is a novel alternative that has not yet been investigated in the literature. To ensure optimal performance, the parameters of the RPIDD 2 controller are optimized using metaheuristic algorithms, including the flood optimization algorithm (FLA), reptile search algorithm (RSA), particle swarm optimization (PSO) and differential evolution (DE). A new approach is proposed which combines the quadratic interpolation optimization (QIO) algorithm with the RPIDD 2 controller, taking advantage of the fast convergence, low computational cost and high accuracy of QIO. Comparative analyses between QIO-RPIDD 2 , FLA-RPIDD 2 , RSA-RPIDD 2 , PSO-RPIDD 2 and DE-RPIDD 2 controller are performed by evaluating performance metrics such as transient and frequency response. The results show that QIO-RPIDD 2 achieves superior performance, adapts quickly to different reference temperatures and performs excellently on key performance indicators. These results make the proposed QIO-RPIDD 2 controller a promising solution for industrial temperature control and contribute to more efficient and adaptive optimization techniques.
