In a fluidic control system generating a fluidic rate signal indicative of rate of movement of a body in a preselected direction, wherein said body has a characteristic natural bending frequency as said body moves in said direction; a fluidic notch filter for reducing said fluidic rate signal to a minimum value at said natural frequency, comprising: sensor means operably coupled with said body for generating a fluidic acceleration signal indicative of acceleration of said body in said direction, said sensor means having a mass with a natural frequency approximately equal to said body natural frequency, the magnitude of said fluidic acceleration signal being approximately equal to the magnitude of said rate signal at said natural frequency but substantially less at other frequencies; and fluidic circuit means for combining said rate signal and acceleration signal to reduce said rate signal to said minimum value at said natural frequency.
