15.7 Conclusions
This chapter presented an inexpensive but effective HIL platform. By using open-
source solutions both in respect to hardware (Arduino) and software (FAST) the
capabilities to modify the proposed HIL platform are greatly broadened and allow
novel ways of interaction between the developers and end users [ 6 ]. Active user
communities
exist
around
Arduino
( http://arduino.cc/playground )
and
FAST
( http://wind.nrel.gov/forum/wind/viewforum.php?f=4 ).
In conclusion, the HIL proposed platform was found to be suitable for control
system testing. It can be used to characterize the behavior of wind turbines in
normal operation as well as in fault operation. The low-cost and ease of use makes
it attractive in educational and research environments with limited budgets, and in
particular for researchers, students, and universities with limited resources.
