These reference signals can be readily generated from a tachometer signal from the Taking the Laplace transform of Eq. (4.54), we get the following expression for the transfer function of the dc tachometer: = K (4.55) The unit of K is V/krpm. Typically, K value is ~ 6 V/krpm. As in dc generators, the ac output is converted to dc by a commutator. To filter.out the carrier frequency, a phase sensitive demodulator can be used in the output which has the form of = e(t)smcoct (4.57) The forms of the modulated signal and the final filtered output are shown in Figure 4.45.In a hydraulic servo valve feed drive, pump pulsations of 500Hz traveled through the machine piping to the servo valve, the hydraulic motor, and finally the feedback tachometer of the velocity loop. The high sensitivity of the tachometer (100V/1000rpm) sensed the 500Hz vibration and generated this voltage into the servo drive electronics, where it was amplified through the entire drive, causing an undesirable vibration. A 500Hz notch filter at the tachometer output feed to the servo In a position plus velocity servosystem.of a mechanicalpositioning device, the tachometer signal is connected to a feedback control circuit with equivalent resistance 2 kV. Estimate the percentage The purpose is to actively filter out the cyclic excitation forces generated by the internalcombustion engines before they would adversely vibrate the components such as seats, floor, and steering column, which come into contact with the vehicle occupants (see Chapter 12).

Kirtley, Jr. Abstract This work develops a hardware realization of a median filter suitable for use in realtime control and monitoring applications in power electronic circuits. Median filters have.the ability to suppress impulse noise in signals while preserving underlying edges. New offline results in this section show the result of filtering a noisy motor tachometer signal with the median filter, suggesting one potential realtime application. Section III details some AngularAcceleration Feedback Loop Angular acceleration of the forearm was obtained by differentiating the tachometer signal, as indicated by the differentiator/filter circuit of Fig. 12. The linear representation of this system is given by the following transfer function: £ (B) = RCS (4.1) (RCS + 1) where u = differentiator input y = differentiator output S = Laplace transform operator + 10 VOLTS > or o MOTOR SWITCH POT 9 40 B Method of Load Application.AngularAcceleration
