Abstract
The invention relates to a monitoring unit (5) for monitoring a first control value (Inom) for overshooting or undershooting of a threshold value (Imax), with the first control value (Inom) being used for controlling an apparatus (3). The monitoring unit (5) in this case has determination means (10, 20, 30, 40, 45) for determining the threshold value (Imax) from an instantaneous value (Is) of the first control value (Inom) when the apparatus (3) reaches a predetermined operating state, and monitoring means (50, 60) for monitoring the first control value (Inom) for overshooting or undershooting of the determined threshold value (Imax) after the apparatus (3) has reached the predetermined operating state.
Claims11
A monitoring unit (5) for monitoring a first control value (Inom) for overshooting or undershooting of a threshold value (Imax), with the first control value (Inom) being used for controlling an apparatus (3);
- having:
- determination means (10, 20, 30, 40, 45) for determining the threshold value (Imax) from an instantaneous value (Is) of the first control value (Inom) when the apparatus (3) reaches a predetermined operating state, and
- monitoring means (50, 60) for monitoring the first control value (Inom) for overshooting or undershooting of the determined threshold value (Imax) after the apparatus (3) has reached the predetermined operating state.
A control system for an actuator (3), having:
- a regulator (1) which receives, as input variables, a nominal value (Nnom) of an operating parameter for the actuator (3), and an actual value (N) of the operating parameter from the actuator (3), and which supplies, as its output, a first control value (Inom) for the actuator (3),
- characterized by a monitoring unit (5) for monitoring the first control value (Inom) for overshooting or undershooting of a threshold value (Imax), in which case the monitoring unit (5) has:
- determination means (10, 20, 30, 40, 45) for determining the threshold value (Imax) from an instantaneous value (Is) of the first control value (Inom) on reaching a predetermined operating state, and
- monitoring means (50, 60) for monitoring the first control value (Inom) for overshooting or undershooting of the determined threshold value (Imax) after the actuator (3) has reached the predetermined operating state,
- in which case the determination means (10, 20, 30, 40, 45) has a first identification means (20) for monitoring the nominal value (Nnom) of the operating parameter of the actuator (3) for identification of the predetermined operating state of the actuator (3), and if the first control value (Inom) overshoots or undershoots the determined threshold value (Imax), the monitoring unit (5) locks the actuator (3) (LOCK) when said actuator (3) reaches the predetermined operating state.
