Development of tuning free SISO PID controllers for First Order Plus Time Delay (FOPTD) and First Order Lag Plus Integral Plus Time Delay model (FOLIPD) systems based on partial model matching and experimental verification

Modeling and Control of Beer Fermentation for Optimal Flavor and Performance

“…The observations indicate that the method of Yerolla and Besta [66] provides superior servo and regulatory responses compared to the other two approaches. The internal model control (IMC) approach [65] has a faster settling time, but the behavior of the manipulating variable is not smooth, which is essential for the final control element; thus, the control technique of Yerolla and Besta [66] is superior for regulating the beer fermenter jacket temperature. The analysis of the performance indices in Tab.…”

“…The higher-order transfer function model gives the better fit to the actual dynamic process, but for designing the PID controller a complex tuning method is required. For a first-order plus time-delay process (FOPTD), the PID controller can be easily designed by using the methods described in [65][66][67], without any fine-tuning parameters. So, we considered the FOPTD model for further studies in the present work.…”

“…The controller studies were undertaken for the FOPTD model. To examine the servo and regulatory responses and performance indices, three controller techniques were used [65][66][67].…”

Future Trends for a First Course in Control Engineering

“…The advent of cheap micro-computing means that laboratory provision can be much cheaper and more accessible, thus providing opportunities for an increased presence in the curriculum. A notable innovation that is beginning to grow in popularity in the past few years is the concept of take home laboratories (Oliveira and Hedengren, 2019;Rossiter et al, 2019;Oliveira et al, 2020;Yerolla and Besta, 2021), that is cheap (often as little as $30 per kit) and transportable mini-kits that students can borrow for many weeks and use for independent learning and investigation. Having 24/7 access to real hardware with rapid runtimes and driven by a laptop allows students to get a real feel for authentic issues.…”
