Abstract
A velocity detector for a sled motor is provided. Specifically, the velocity detector contains a multiplexer, a differentiator, a first amplifier, an integrator, a second amplifier, and a third amplifier. The multiplexer inputs a plurality of velocity signals and multiplexes the velocity signals to produce a multiplexed signal, and the differentiator differentiates the multiplexed signal to produce a differentiated signal. The first amplifier amplifies the differentiated signal to produce an amplified signal, and the integrator integrates the amplified signal to produce an integrated signal. The second amplifier amplifies an applied signal to produce an amplified applied signal, and the amplified applied signal and the integrated signal are combined to produce a resultant signal. The third amplifier inputs the resultant signal and amplifies the resultant signal to produce a velocity detection signal. In addition, a method performed by the velocity detector is also provided.
