“…In order to make this article as self-contained as possible, this section present an overall portrayal of the system to be controlled. Interested readers can find a more thorough description of the prototype at [1]. Figure 2 represents a complete overview of the instrumentation, actuation and control loops actually implemented.…”

“…When in automatic mode, the movement speed of the cart depends on the sewing machine operation where an embedded digital proportional-integral (PI) controller closes the loop between the measurement speeds and the sewing station movement. In [1], the dynamics of the prototype was obtained by means of its step response and the derived mathematical model was employed to https://www.degruyter.com/view/j/cjece estimate the controller parameters. Using the system transfer function, the PI gains were adjusted using a classical Bode plot reshaping technique.…”

“…The use of evolutionary-based techniques for control systems design are well-established methods in the literature which can be used to automate the tuning process in the present reference frame. This paper follows from [1] and describes the steps and results obtained through the use of evolutionary-based algorithms (EA) for proportional-integral-derivative (PID) controller tuning in the context of the sewing station prototype. The article is divided into seven sections.…”

Development of increasingly efficient production methods is a competiveness driving factor for any company. Today, many of these improvements include the integration of technology-based solutions into processes traditionally operated by humans. In this context, the present work aims to report the controller performance of a prototype developed for semi-automatic sewing stations. This project was fostered by “Factory Play”, a Portuguese company that produces inflatable structures, under the technical supervision of the Polytechnic Institute of Bragança. At the present time, the sewing station travel speed is regulated by an embedded PID controller that has been previously tuned using classical methods. However, even if the overall performance is currently acceptable, additional experiments were made regarding the use of evolutionary based algorithms to attain a better dynamic response and flexibility. This article present the results obtained using those methods where it is possible to confirm that the use of evolutionary algorithm will simplify the design process while consistently leading to a suitable solution.
