“…In order to amend the performance, modified IMC structures have been proposed by various authors [1,11,12]. Further, it is also proposed to reinforce IMC-PID method by utilizing fractional filter [13][14][15]. Several other methods with some homogeneous attributes and diversities have withal been studied such as Direct synthesis method [10,16], Equating coefficient method [17], Two degree of freedom(2DOF) control scheme [18,19], optimization methods [20,21].…”

The Effective control of integrating processes with dead time is always a challenging task. Many researchers have addressed this by proportional-integral-derivative (PID) controllers derived through various procedures such as internal model control (IMC), Direct synthesis etc. This paper presents the design of PID controller associated with a 2/3 order filter for integrating processes with dead time. In this study, a polynomial technique is used to obtain the PID parameters and filter coefficients. The maximum sensitivity (MS) criteria is utilized for the selection of the tuning parameter. Second-order Pade's approximation is utilized for dead time approximation. To bring down the overshoot and obtain faster settling time of servo response, a set point filter is employed. The set point filter provides manipulation of servo response without altering regulatory performance. Simulation studies are carried out on some of the bench marking process models used in the literature. The developed control design provides ameliorated closedloop performance, particularly in terms of disturbance rejection. The proposed controller is relatively robust which is evidenced by performance metrics.

“…In Reference [97], analytical tuning rules for a 2-DOF PID controller, where overall optimal closed-loop response is obtained via two-step tuning of the closed-loop transfer function, were proposed. Controller designs based on IMC PID tuning rules were proposed in References [8,34,[67][68][69][70]107]. In Reference [71], a modified IMC design based on a 2-DOF control structure that allows the separate optimisation of tracking and disturbance-rejection performance was proposed.…”

Parametric and Nonparametric PID Controller Tuning Method for Integrating Processes Based on Magnitude Optimum

Integrating systems are frequently encountered in power plants, paper-production plants, storage tanks, distillation columns, chemical reactors, and the oil industry. Due to the open-loop instability that leads to an unbounded output from a bounded input, the efficient control of integrating systems remains a challenging task. Many researchers have addressed the control of integrating processes: Some solutions are based on a single closed-loop controller, while others employ more complex control structures. However, it is difficult to find one solution requiring only a simple tuning procedure for the process. This is the advantage of the magnitude optimum multiple integration (MOMI) tuning method. In this paper, we propose an extension of the MOMI tuning method for integrating processes, controlled with a two-degrees-of-freedom (2-DOF) proportional–integral–derivative (PID) controller. This extension allows for calculations of the controller parameters from either time domain measurements or from a process transfer function of an arbitrary order with a time-delay, when both approaches are exactly equivalent. The user has the option to emphasise disturbance-rejection or tracking with the reference weighting factor b or apply two different reference filters for the best overall response. The proposed extension was also compared to other tuning methods for the control of integrating processes and tested on a charge-amplifier drift-compensation system. All closed-loop responses were relatively fast and stable, all in accordance with the magnitude optimum criteria.
