Abstract
An antiskid braking system includes an improved apparatus for generating a lead signal to provide lead compensation. According to one feature of this apparatus the gain is a function of the algebraic sign of the input signal to the apparatus. Preferably, higher gains are used when the input signal corresponds to wheel deceleration than when it corresponds to acceleration. Another feature of the invention is that the apparatus operates to reduce the magnitude of the lead signal when it exceeds a limit value, preferably by clamping the lead signal to a maximum magnitude. A third feature is that first and second order lead signals are utilized in such a way as to preclude adverse cancellation between the two.
