Iterative Feedback Tuning Algorithms for Two Rotor Aerodynamic Systems

Iterative Feedback Tuning (IFT) is one of the earliest algorithms from the data-driven class that was pioneered by Hjalmarsson et al. The current book chapter aims to propose and validate via experiments the IFT algorithms on the Two Rotor Aerodynamic System (TRAS) laboratory equipment for Single Input–Single Output (SISO) control structure. Therefore, the IFT algorithm is applied in SISO control system configuration specifically in the context of IFT-based tuning of Proportional–Integral controllers by controlling separately the azimuth and the pitch position of the TRAS. This chapter is dedicated to Acad. Florin Gheorghe Filip, to celebrate his 75th anniversary and also his 15th anniversary as the Chairman of the Information Science and Technology Section of the Romanian Academy.
