[Peter]’s variable pitch rotor system is basically an electronic prop mount that connects directly to the driven shafts on his gas-powered quadcopter. To get power to the electronics ...

A propeller is a rotating airfoil that produces thrust by accelerating air behind it. The amount of thrust depends on the shape, size, and angle of the propeller blades, as well as the speed of ...

Lately, interest in pitch angle control has revived, now combined with variable speed operation. This renewed interest is due to the growing concern about mechanical loads and power quality [2, 30].

This one focuses on fixed-pitch WECS, whereas the following one deals with variable-pitch ones ... controller begins with the derivation of an LPV model for the nonlinear system. Then, the design ...
