Patent number: 9116516Abstract: Information from a real sensor and a virtual sensor are fused to form a hybrid sensor. Control signals (and/or the absolute value of the control signals) applied to an actuator are accumulated and converted to a position the actuator should be in based on the accumulated control signals to form the virtual sensor. The actuator position from the virtual sensor is fused with an actuator position from a real sensor to form the hybrid sensor. Small periodic corrections can be made to the accumulating control signals to maintain or achieve, if possible, correlation between the virtual sensor and the real sensor over time. The corrections slowly decrement errors in the actuator position indicated by the virtual sensor. Accumulating numerical errors in the accumulating control signals are reduced and the significance of long past events is de-emphasized by a forgetting factor (kff) used at defined periods of time (tff).Type: GrantFiled: June 26, 2012Date of Patent: August 25, 2015Assignee: ABB Technology AGInventor: Francis P.
