Abstract : The patent relates to a device whereby a pneumatic wheel speed sensor provides pulse frequency signal proportional to wheel speed, the signal is converted to DC signal and differentiated and compared to commanded deceleration, error which causes modulation of brake pressure. Excessive decleration causes a digital amplifier to switch into the system an integrator resulting in rapid brake pressure signal decrease. A second order lead protects against undesirable landing gear oscillation in aircraft applications.
