    This paper proposes a hybrid Posicast-based proportional-integral-derivative with proportional-derivative-acceleration (PID-PDA) controller for temperature regulation in delay-dominant continuous tunnel kilns. The controller is developed based on a system-identified second-order-plus-dead-time (SOPDT) model derived from industrial data and implemented in discrete time for programmable logic controllers (PLCs). A unified framework enables comparison with a standard PLC-based proportional-integral (PI) controller, an internal model control (IMC)-tuned PI controller, and a Smith Predictor-PI controller under identical conditions. Simulation results demonstrate faster response, negligible overshoot, and reduced tracking error, with improved settling time and lower, integral of absolute error (IAE), integral of squared error (ISE), and integral of time-weighted absolute error (ITAE), while maintaining comparable control effort. Robustness analysis confirms stable performance under plant perturbations, with IAE variations within approximately ± 10 (servo) and ± 1 (disturbance). The controller is validated on an Allen-Bradley PLC in a silicon controlled rectifier (SCR)-based heating system. Experimental results show improved steady-state performance, including reduced bias, lower mean absolute error (MAE) and root mean squared error (RMSE), reduced oscillation amplitude, and compliance within the ± 1 temperature band. The proposed approach provides a practical, robust, and high-performance solution for upgrading existing PLC-based systems without hardware modifications.

    This paper proposes a successful technique for designing a PIDA (proportional-integral-derivative-acceleration) controller in both continuous-time and discrete-time frameworks, which provides better transient response specifications in comparison with PID (proportional-integral-derivative) controller for third-order plant. The proposed design technique consists of three major steps. First, the PIDA controller is designed by using Kitti's method based on root locus technique in the control loop. Second, the maximum percentage overshoot can be decreased to satisfy specification by applying the forward controller. Based on these two steps, all desired specifications can be achieved without trial and error method for tuning controller parameters. Lastly, the Posicast controller is simply designed because the controlled system can be approximated as a standard second-order system. The performances of the designed PIDA controller are confirmed through MATLAB simulation results.

    This paper proposes a successful technique to design a discrete-time (DT) proportional-integral-derivative-acceleration (PIDA) controller for third-order plants. The proposed technique consists of three major steps: discretization of the controlled plant using the first-order hold (FOH) method, discretization of the continuous-time (CT) PIDA controller structure using the delayed first-order hold (DFOH) method to achieve the DT PIDA controller structure, and design of the target controller using the Kitti’s method. Simulation results confirm that the controller designed by utilizing the proposed technique provides equivalent performances compared to a conventional CT controller and a DT controller discretized by utilizing the Tustin’s method.
