Cascaded PID Controller Design for Heating Furnace Temperature Control

The paper evaluates the performance of cascaded PID controller designs for the temperature control of an industrial heating furnace. From the control theory literature it is clear that ideal PID controller is an obsolete for the control of non-linear processes like temperature. PID controller in cascaded architecture is the best choice compared to conventional single loop control system for controlling these nonlinear processes. However, it is constrained in choosing the better PID gains. Hence, this paper is such an approach to set the better values of PID gains in cascaded form by evaluating the performance with conventional tuning formulas. Performance analysis of various algorithms was carried out by finding the system’s dynamic performance characteristics in each case. The entire system is modeled by using MATLAB/Simulink, The simulation results indicate that the proposed cascaded PID design could results to rapidity in response with robust dynamic performance.
