“…Several works have been written on the tuning of PID/PI controllers [6,7]. Using tuning rules is the most direct way to set up controller parameters [6]. Many of these rules are based on a simple model of process dynamics and, in particular, the widely adopted plant model is the first order plus time delay (FOPTD) [3,8].…”

Engineering education and, particularly, control engineering, has shown growth in research and development activities during last years. Currently, proportional–integral (PI) and proportional–integral–derivative (PID) controllers are the most commonly used in industrial process applications. Nonetheless, it is reported that many of them are badly tuned. From an educational perspective, it is crucial for the student to understand the importance of tuning a control loop correctly. This paper presents an interactive tool focused on the study of PI controllers. The tool provides a set of tuning rules for both open-loop stable and unstable first order plus time delay processes. The different tuning rules can be compared interactively by the user, allowing a critical analysis of basic concepts about stability, robustness, and performance in PI control loops. In addition to educational purposes, the tool has been developed, taking into account practical considerations, such as simulation with a controller discrete implementation, process input saturations, and windup effect. We evaluated students’ achievement in the final examination in the Automatic Control course of the Electronics Engineering degree. Students showed significant improvement in their understanding of PI controller design. A survey and a practical case study were performed to evaluate the effectiveness of the proposed tool.

“…Historically, there were proposed a great number of methods for the calculation of parameters of controllers, but most of them require significant expenditures of time and do not always yield a satisfactory result, which would ensure the The search for methods to improve tuning a PID-controller is still under way. Specifically, author of [4], by way of generalizing the disarranged terminology in the calculation of controllers, proposed the unified rules for tuning PI and PID-controllers taking into consideration a zone of insensitivity, though any information on other types of nonlinearities is missing. While developing the subject of non-linear controllers, authors of ref.…”

“…is used here and shown to be applied to a wide range of overdamped processes including processes for which FOPTD models suffer in tuning PI controllers. Like the FOPTD model is used successfully for higher order processes, the proposed HOPTD model can be applied to processes with β higher than 0.5.…”

“…Proportional‐integral (PI) controllers are still used widely in practice due to their simplicity and are covered in detail in almost all process control textbooks . The PI controller gain and integral time can be designed based on the first‐order plus time delay (FOPTD) model . The FOPTD model has three parameters (process gain, time constant, and time delay) and many PI controller tuning rules based on FOPTD model parameters are available.…”

Half order plus time delay (HOPTD) models to tune PI controllers

Methods based on the first‐order plus time delay (FOPTD) model are very popular for tuning proportional‐integral (PI) controllers. The FOPTD model‐based methods are simple and their utility has been proved with many successful applications to a wide range of processes in practice. However, even for some overdamped processes where the FOPTD model seems to be applied successfully, these empirical FOPTD model‐based methods can fail to provide stable tuning results. To remove these drawbacks, a PI controller tuning method based on half‐order plus time delay (HOPTD) model is proposed. Because FOPTD model‐based methods can be applied to higher order processes, the proposed HOPTD model‐based method can be applied to higher order processes as well. It does not require any additional process information compared to the FOPTD model‐based method and hence can be used for overdamped processes in practice, complementing the traditional FOPTD model‐based methods. © 2016 American Institute of Chemical Engineers AIChE J, 63: 601–609, 2017
