<p>The invention relates to a method and a system for evaluation whether oscillations in a control process depend on static friction in an actuator. The method comprises the step: measuring the signal from the actuator or the signal from the process; signal processing the measured signal for the purpose of detecting whether the measured signal comprises abrupt inclination changes; and deciding whether there is static friction in the actuator based on whether the signal comprises abrupt inclination changes. Further the invention comprises a computer program product loadable into the internal memory of a computer, comprising software code portions that perform the method when it is run on a computer.</p> |
