    摘要： The invention relates to a method for processing sensor data transferred from at least one asynchronous sensor (10) to an intermediate memory (110) at a data transfer rate (Tpas), said sensor data being read out of the intermediate memory at a pre-determined scanning rate (Tsg). An average value (SM) is calculated from a pre-determined quantity of read-out sensor data. According to the invention, the ratio of the data transfer rate (Tpas) to the scanning rate (Tsg) is selected in such a way that the quantity of sensor data averaged within a scanning period is n or (n+1). The average values (SM) of the read-out sensor data are calculated with a fixed synchronised phase displacement, in relation to the scanning rate (Tsg), which is determined by the averaging of (n+1) sensor data, n being a natural number greater than or equal to two.

    摘要： A plant controller controls a plant modeled in a discrete-time system. The controller uses a frequency-shaping response-designating control algorithm having a filtering function to cause a difference between output of the plant and a target value to converge. Thus, the plant is robustly controlled without causing undesired frequency components. When the plant is an engine, the engine is modeled using a ignition timing corrective quantity as input and a rotational speed as output. The controller performs the frequency-shaping response-designating control algorithm to determine the ignition timing corrective quantity. The frequency-shaping response-designating control may be frequency-shaping sliding-mode control. In one embodiment, the control input into the plant may includes a corrective term for stabilizing an internal variable of the filter, a corrective term for stabilizing the difference between the output of the plant and the target value and a corrective term that varies depending on a switching function.

    摘要： The invention relates to a method for monitoring at least one measuring signal, in particular for use in automation technology, production automation and process automation. Said method automatically determines and establishes an optimal time interval between measuring periods, by means of the course of a measuring signal. According to the invention, a computer system cyclically determines a characteristic value of the measuring signal in measuring periods (8), which are separated by a time interval (9), whereby a priority (P1...P15) is automatically defined, said priority (P1...P15) is assigned to the measuring signal and the time interval (9) between the measuring periods (8) is defined in accordance with the priority (P1...P15).

    摘要： A servo control apparatus and method controls systems at least partially on the basis of an observable variable that has an absolute value functional relationship with the controlled variable and does not change sign for positive and negative variations from a nominal value. When applied to the positional control of an object, the control system observes a value of a position error signal and maps (148) that signal to two different potentially correct displacement values. Two estimators (150, 152) within the control system are initiated, one using the positive displacement and the other using the negative displacement, and the two estimators each predict the future position of the object and the corresponding position error signal for each estimated position. A new position error signal is detected and compared to the two estimated position error signals. After sufficient system evolution, the control system can select one or the other of the estimators as being correct and the associated displacement is identified as correct and is used for future positioning applications, preferably until the sign of the displacement of the head again becomes ambiguous. The control system can be used in combination with other control mechanisms including those using complimentary control information that provides more complete positioning information. The control method, system and apparatus find particularly advantageous application in magnetic storage hard disk drive systems.

    摘要： In a control system a characteristic quantity of a process (1) exhibits a periodic disturbance. A measuring system (2) generates a measuring signal (Vm) which represents the characteristic quantity. A control device controls the process in response to the measuring signal (Vm). To reduce the periodic disturbance, the control device (3) comprises a delay circuit (4) which delays an input signal (Vin) related to the measuring signal (Vm) by a time interval (T) having the length of a period (Tp) of the periodic disturbance. The control device (3) comprises an analysis circuit (6) for deriving an analysis signal (Va) which is indicative of a deviation between the period of the periodic disturbance and the delay time. By means of a control circuit (13) and an adapter circuit (7), the delay time (T) is set in dependence on the analysis signal (Va) to a value for which the analysis signal (Va) indicates that the delay time (T) is equal to the period (Tp). A correlation system can be used for deriving the analysis signal (Va).

    摘要： Die vorliegende Erfindung betrifft ein Verfahren zum Regeln einer Ausgangsgröße eines Prozesses mit großen Totzeiten und Verzögerungszeiten, beispielsweise zum Regeln der Innenraumtemperatur eines Absorberkühlschrankes, sowie eine Vorrichtung zur Durchführung eines solchen Verfahrens. Die Ausgangsgröße des Prozesses, etwa die Innenraumtemperatur, wird abgetastet und mit einem Sollwert verglichen, um eine Sollwertabweichung zu ermitteln. Abhängig von der ermittelten Sollwertabweichung wird eine Stellgröße, etwa die dem Absorber zugeführte Leistung, derart berechnet, daß die Ausgangsgröße des Prozesses an den Sollwert herangeführt wird. Nach Verstreichen einer Wartezeit wird erneut ein Wert der Stellgröße bestimmt. Während der Wartezeit wird die Stellgröße nicht verändert. Die Wartezeit wird auf der Grundlage der Differenz zwischen dem Wert der Stellgröße und einem früheren Wert der Stellgröße berechnet. Ein Regler zur Durchführung des Verfahrens umfaßt einen Speicher für eine früher berechnete Stellgröße sowie einen Zeitgeber, der ausgebildet ist, den früher berechneten Wert der Stellgröße und den aktuellen Wert der Stellgröße zu empfangen, aus diesen eine Wartezeit zu berechnen, und nach Verstreichen dieser Wartezeit eine erneute Berechnung eines Wertes für die Stellgröße auszulösen.
