To limit motion in an electromechanical system, an input signal is filtered using an adaptive filter, such as an infinite impulse response filter, to yield a predicted motion, and the input signal is attenuated by an amount controlled by the predicted motion. The filtering may further yield a predicted temperature, and the amount of attenuating may be further controlled by that temperature. Components of the input signal at selected frequencies may be removed, and a portion of the input signal from which the components have been removed may be mixed with a portion of the input signal from which components have not been removed. The removing of components at selected frequencies may include applying a notch filter, and the two portions may be equalized. phase-adjusting the unfiltered portion to account for phase delay introduced by the notch filter. The notch filter may operate at a resonant frequency of the system.
