“…Moreover, the infinite number of poles in s-domain, caused by time delay, can be transformed into the finite number of poles in z-domain by taking advantage of discretetime domain representation. Since no approximation is used for the time delay term, stability analysis and controller design is done easily [5].…”

In this paper, a linear control technique based on a PID controller, which is the most used controller type in the industrial applications, is proposed for the angular position control of fan and plate system that has a nonlinear characteristic. Although the system is nonlinear, in the experimental studies, it is observed that for any small region in which the system can be considered as linear, the system (the linear model obtained around an operating point) has the same characteristic in the all operating regions. A new control approach is proposed by using this property of the system to guarantee the stability and operation without any overshoot.

“…Although these higher-order models are very precise, for control purposes, they are not to be used. In majority of cases, a linear first-order system with dead time element representation is used to model the behavior of the higher-order models (Eris & Kurtulan, 2011;Kurtulan & Goren, 2005).…”

“…They can compensate the effect of both the delayed and non-delayed processes. It is important to note that the cost benefit ratio achieved through the PID controller is not easy to achieve with other controllers (Eris & Kurtulan, 2011;Gopi Krishna Rao, Subramanyam, & Satyaprasad, 2013;Lee et al, 2008;Pai et al, 2010;Shamsuzzoha & Lee, 2008a). An observation indicates, 97% of the regulatory controllers use a PID algorithm (Desborough & Miller, 2001).…”

The internal model control (IMC) proportional integral derivative (PID) controller tuning rules provide an excellent tracking of set-point, but sluggish disturbance rejection, as the conventional IMC filter introduces slow process pole. Disturbance rejection is significant than set-point tracking in many industrial applications. This paper proposes the design of IMC-PID controller, cascaded with lead-lag filter, with an improved IMC filter to provide effective disturbance rejection and robust operation of the first-order processes (FOPs). The simulation study was conducted to show the effectiveness of the proposed method on various structures of the FOPs, calculating the controller parameters, maintaining similar robustness in terms of maximum sensitivity M S . Perturbations were incorporated in the parameters of the plant model simultaneously, for the robustness analysis of the controller. The closed-loop performance was evaluated with the integral error criteria, namely, integral absolute error, integral square error, and integral time absolute error. The proposed IMC filter provided good disturbance rejection. The results of recently published design methods were compared with that obtained from the proposed method, validating the usefulness of the proposed method.

“…PID can compensate the effects of processes with delay and no delay. A study has indicated that 97 % of the controllers in the industry use PID algorithm for regulator operation (Lee et al 2008;Pai et al 2010;Eris and Kurtulan 2011;Gopi Krishna Rao et al 2013;Desborough and Miller 2002). The IFAC Conference on Advances in PID Control held in Brescia (Italy) during 28-30 March 2012 concluded that there is no perfect alternative to the PID controller at least at the bottom layer in the process industries (Alcántara et al 2013;Shamsuzzoha 2014).…”

The aim of this work was to obtain a design for the proportional integral derivative controller in series with a second-order lead/lag filter for pure integrating process with time delay based on internal model control principle to achieve efficient disturbance rejection and robustness. A setpoint filter is introduced to reduce the overshoot in the setpoint response. Further, the robustness of the controller is examined by incorporating perturbations in the time delay parameter for model mismatch. The proposed method demonstrated good disturbance rejection and robustness in comparison with recently developed methods with the controller tuned to have same robustness rank with the calculation of the peak of maximum sensitivity (M S ).
