1. An apparatus for controlling a tilt rotor including a motor and a rotor blade, the apparatus comprising:
a thrust command generator configured to receive an input of a throttle command and generate a first collective pitch angle based on the throttle command;
a rotation speed compensator configured to generate a compensation value based on a target rotation speed and a current rotation speed of the motor;
a compensation weight generator configured to generate a first weight value and a second weight value according to a flight speed;
a collective pitch angle command generator configured to generate a final collective pitch angle adjustment command for the rotor blade, based on a first compensation value and the first collective pitch angle, the first compensation value being obtained by multiplying the compensation value by a preset conversion ratio (col/esc ratio) and the first weight value; and
a motor controller configured to generate a motor control command based on a second compensation value and the first collective pitch angle, the second compensation value being obtained by multiplying the compensation value by the second weight value.
