What is a Truncated Angle Variant (TAV)?

Truncated Angle Variant(TAV) method is to truncate the derivative function of the error components until the feedback phase nearly matches the input signal of the controller. This truncation method examines the phase difference between the feedback and input of the controller. This tunes the derivative and integral parameters that reduce the error signal and provides better controlling speed to the motor. This truncation helps to reduce the delay and improves more accuracy.
