A control device (1) for controlling a control target comprising an astatic system (2) that has dead time is provided with: a dead time compensation system (5) that compensates for dead time at the control target based on the dynamic characteristics of the control target; and an integration error compensation system (6) that compensates for integration errors originating in the dead time compensation system (5). The integration error compensation system (6) comprises: an ideal response unit (7) in which the dynamic characteristics of the control target while in a state in which interference is not input are used as a model; and a correction unit (8) that is configured to correct a comparative value for the output of the ideal response unit (7) and the output of the control target and subsequently input the result to the control target.

An object is to provide a signal processing device capable of reducing a sudden change in the rate of change of an output signal at the time of switching between two signals. In the signal processing device, when a signal of a larger value is selected, a smoothing signal is generated based on the deviation between two signals such that the smoothing signal has a value larger than the values of the two signals between two points at which the smoothing signal intersects the two signals, or when a signal of a smaller value is selected, the smoothing signal is generated based on the deviation between two signals such that the smoothing signal has a value smaller than the values of the two signals between two points at which the smoothing signal intersects the two signals.

A method for a household electrical appliance to perform mode switching includes detecting whether a user is in a sleeping state, switching a current operation mode to a silent mode if the user is in the sleeping state, and operating in the silent mode.

To provide a feedback control device that achieves smooth continuous control at the time of switching of binary feedback controls. When, as a result of constant current feedback control being performed through a connection between a current control unit 12 and an I control unit 24, a detected measured voltage value of a control object 21 reaches a preset value that is maintained by constant voltage feedback control, a u1/u2 determination unit (switching determination unit) 27 controls changeover switches 22 and 23 to connect a voltage control unit 15 and the I control unit 24 and, in addition, connect the voltage control unit 15 to an adder 25 to which the I control unit 24 is connected, and performs switching to constant voltage feedback control.

To be able to activate a smoothing filter for a setpoint, with which the movement of a drive axis (A, Ai) of a drive unit (AE) can also be controlled during the movement without a negative effect on the movement, it is provided that the smoothing filter (10) is initialized with a setpoint profile (S.sub.init) so that a current movement phase ((S.sub.0, {dot over (S)}.sub.0, . . . , S.sub.0.sup.(x))) is continued continuously and the repeated time derivative (S.sup.(x+1)) of the highest time derivative (S.sup.(x)) of the setpoint (S(t), S(k)) is limited.

Disclosed is an industrial control device including a point-to-point backplane/point module architecture providing RIUP (Removal and Insertion Under Power) functionality where data communications between modules is maintained after the removal of a point module from the backplane. According to an exemplary embodiment, a backplane includes a plurality of bypass switches controlled by respective point modules, whereby data communicated bypass a removed point module interface and point-to-point data communications are provided to an inserted point module after an initial routine is executed by a microcontroller associated with the inserted point module.

Systems and methods are described for presenting information for managing a vital sign of a patient. A graphical user interface (GUI) can be presented that displays information concerning a vital sign of a patient, including the most current value of the vital sign received and past values of the vital sign over an elapsed time period. Using this information, a time in target value can be generated representing an amount of elapsed time the patient's measured vital sign was within a predetermined range. Preferably, the systems and methods are used with a closed-loop system that may automatically adjust a dosage rate of a medication, although manual control is also contemplated. The GUI may comprise one or more visual indicators presented on the historical data that, when selected, present additional information that may be useful to managing the care of the patient.
