This paper defines a variable transfer function that is used to compensate for low frequency structural resonances in a turret so that stabilization of a closed loop servo system can be achieved. Three circuits for implementing this compensation are presented. They are: the feedforward three amplifier biquad, the summing four amplifier biquad, and the single amplifier biquad with pole-zero cancellation. Design equations allowing the engineer to go directly from the given transfer function to the actual component values are developed for each circuit. A comparison of the final circuit designs is also presented.
