Servomechanism error handling

Abstract:

Techniques for error handling by a servomechanism are disclosed. The servomechanism determines, based on a first set of values assigned to servomechanism variables, electrical signals for controlling a component during a particular time interval, and applies the electrical signals to move the component. Subsequently, the servomechanism measures values for attributes associated with the component. Based on the measured attribute values, the servomechanism computes a second set of values for the servomechanism variables. Responsive to determining that the measured attribute values are erroneous, the servomechanism refrains from modifying the electrical signals based on the second set of values for the servomechanism variables.
