    摘要： Es ist eine Anordnung und ein Verfahren zur Temperaturkompensation eines Widerstands (19') angegeben. Ein bezüglich seines Widerstandswerts steuerbarer Widerstand (19') wird mit einem Referenzwiderstand (29) verglichen, der als Switched-Capacitor ausgebildet ist. Ein Vergleicher (27) vergleicht beide Widerstandswerte miteinander. In Abhängigkeit von einem Fehlersignal steuert der Vergleicher (27) den steuerbaren Widerstand (29') sowie einen weiteren steuerbaren Widerstand (19) in einem Nutzsignalpfad an. Somit ist ein temperaturstabiler Widerstand geschaffen.

    摘要： A method, system, and computer program are provided for operating a valve using a cushion filter. The method, system, and computer program receive a process variable signal associated with operation of a valve. The method, system, and computer program filter the process variable signal to produce a filtered process variable signal using a cushion filter. The cushion filter implements a cushion in a bias used by the cushion filter. The method, system, and computer program generate an output signal for adjusting the valve based at least partially on the filtered process variable signal.

    摘要： The present invention relates to a method and a device for executing phase compensation in a control system of a motor-driven vehicle, in which the time derivative for an output signal (y) from a circuit (1) contained in the control system is limited relative to the time derivative for an input signal (u) to the circuit (1) if the time derivative for the input signal (u) exceeds a predetermined value. An error signal (ε) is formed between the output signal (y) and a signal (x) present in the circuit (1), the time derivative of which is not limited in relation to the time derivative for the input signal (u). The error signal (ε) is filtered via an asymptotically stable filter (3) to form a signal (δ), which is fed back and subtracted from the input signal (u) of the circuit (1) to form the signal (x). A conventional rate limiter may be used to form the output signal (y) from the signal (x).

    摘要： A process control apparatus comprises a main controller (22) having a first integrator (32) for integrating a difference signal between a set point and an output of a process and a PD (proprotional-derivative) arithmetic operating unit (34) for executing the PD arithmetic operation for the output of the process. The main controller (22) obtains a control signal on the basis of an I-PD (integral-proportional-derivative) control method and supplying this control signal to the process (20). A robust controller (24), connected to the output of the process (20), comprises a high- order differentiator (44) for highorder differentiating of the process, a second integrator (42) for integrating the difference signal between the set point and the output of the process, a subtractor (46) for subtracting an output of the second integrator (42) from an output of the highorder differentiator (44), and an amplifier (48) for amplifying an output of the subtractor (46) and feeding back this amplified output to the control signal.
