In control systems, hysteresis can be used to filter signals so that the output reacts less rapidly than it otherwise would by taking recent system history into account. For example, a thermostat controlling a heater may switch the heater on when the temperature drops below A, but not turn it off until the temperature rises above B. (For instance, if one wishes to maintain a temperature of 20 °C t… Webb12 apr. 2024 · By considering rotor eccentricity, radial deformation, and hysteresis effect comprehensively as the established model, the calculated radius wear at the 12th hour is 0.05 mm which is close to the experiment value.
