A steady error is a type of error signal that remains constant or slowly changes over time. This is in contrast to spurious errors, which are sudden and unpredictable deviations from the desired setpoint.
Examples of steady errors:
Sensor calibration errors: A sensor might initially read values significantly higher or lower than the actual value. This can be corrected by repeatedly reading the value and adjusting the calibration parameters.
Measurement noise: When measuring a physical quantity, there will always be some random variation in the reading. This can be averaged over multiple measurements to reduce the steady error.
Dead zone error: A system might not operate correctly when its input is outside a certain range. This is also an example of a steady error because the output never reaches the desired setpoint.
Key points about steady errors:
They are characterized by a constant or slowly varying magnitude.
They are usually caused by systematic errors, which are inherent in the system itself.
They are typically easier to control than spurious errors.
They can sometimes be compensated for by adjusting the control parameters
