Precompensates

Precompensates is the present tense third-person singular form of the verb precompensate. In general usage, precompensation refers to applying compensatory adjustments before a known adverse effect occurs, so that the eventual outcome aligns with a desired target.

In control theory and signal processing, precompensation uses a feedforward approach to counteract anticipated dynamics or disturbances by shaping the input accordingly, often in combination with feedback.

In communications and optics, precompensation accounts for channel impairments such as dispersion or nonlinearities by pre-distorting the transmitted signal or by applying digital pre-processing.

In manufacturing and machining, precompensation adjusts tool paths, offsets, or parameters to compensate for tool geometry, wear, temperature, or deflection.

Considerations include the accuracy of models, calibration needs, and robustness, as well as potential increases in design effort and system complexity.
