Evaluation of the PI$$^\lambda $$ Controllers Tuned by Differential Evolution

Abstract

This manuscript proposes a way to tune fractional-order proportional-integral controllers, to synthesize them in hardware and to evaluate them by using hardware-in-the-loop technique. In order to validate the tuned controllers, it was imposed to control a plant where two loops of control were necessary. The obtained results showed satisfactory performance for both designed controllers and proved that fractional calculus can be implemented on high-performance digital processors. Controllers were implemented on the Altera DE2-115 cyclone IV EP4CE115 board.

Validation of Sliding Mode and Passivity Control in High-Power Quadratic Buck Converter Through Rapid Prototyping

“…This choice is due to its ability to provide precise temporal measurements of system response. The Integral Time of Absolute Error (ITAE) index is widely regarded as the most suitable index for use in a quadratic loop [19], [20]. This preference arises because ITAE exhibits higher sensitivity to significant errors while maintaining lower sensitivity to minor errors, making it particularly suitable for systems where the avoidance of large errors is paramount [21].…”
