1. A method for braking a wind turbine including at least one rotor blade coupled to a rotor, said method comprising:
individually controlling an angle of pitch of the al least one rotor blade with respect to a wind direction based at least in part on a design parameter of a component of the wind turbine to facilitate reducing a force induced into the wind turbine component as a result of braking; and
linearly varying a rate of change of the at least one rotor blade pitch angle.
