DIRECT TORQUE CONTROL FOR DOUBLY FED INDUCTION MACHINE-BASED WIND TURBINES UNDER VOLTAGE DIPS AND WITHOUT CROWBAR PROTECTION
This letter proposes a rotor flux amplitude reference generation strategy for doubly fed induction machine based wind turbines. It is specially designed to address perturbations, such as voltage dips, keeping controlled the torque of the wind turbine, and considerably reducing the stator and rotor over currents during faults. In addition, a direct torque control strategy that provides fast dynamic response accompanies the overall control of the wind turbine. Despite the fact that the proposed control does not totally eliminate the necessity of the typical crowbar protection for this kind of turbines, it eliminates the activation of this protection during low depth voltage dips.

Fuzzy controller based FC-TCR System for Flitering purpose
output wave forms:
MAT LAB SIMULATION WAVE FORMS
Fig 1 Wave-forms without compensation for light loads VR>VS as the reactive power generated is greater than absorbed
Fig 2 Wave-forms without compensation for heavy loads VR<VS as the reactive power absorbed is greater than generated

Lot of people will face a definite problem with cleanflight, even i too so i switch to openpilot which reults in better performance of flight. If you want you can reflsh the cc3d with open pilot, even after you flshed the cc3d with cleanflight
follow these simple steps
1. Load the boot loader into the cc3d FC ,you can get it here click here
2.Connect usb cable to your FC.
3.Burn the hex code.
4.Now to update firm ware, go to open pilot gui, click on update and erase the board options like.
5.Disconnect usb cable and it (open pilot) will ask you to connect the cable again.
6.Now it will load the latest firmware automatically.
