Description

Impulsregler mit Impulslängenmodulation Unter der Bezeichnung »Impulsregler« sind Geräte bekannt, die ein Stellglied bei einer Regelabweichung schrittweise verstellen. Die Größe der Regelabweichung beeinfiußt :dabei die Größe eines Schrittes. Diese Schrittgröße kann entweder durch Impulse verschiedener Amplitude (Amplitudenmodulation) oder solche verschiedener Länge (Längenmodulation) gegeben sein. Der zeitliche Abstand zwischen dem Ende eines Impulses und dem Anfang des nächsten Impulses wird mit »Impulspause« und der Abstand zwischen den Anfängen zweier aufeinanderfolgender Impulse mit »Impulsperiode« :bezeichnet.Pulse controller with pulse length modulation Under the designation "Pulse controller" devices are known that adjust an actuator step by step in the event of a control deviation. The size of the control deviation influences: the size of a step. These Step size can either be through pulses of different amplitudes (amplitude modulation) or of different lengths (length modulation). The time interval between the end of an impulse and the beginning of the next impulse with »impulse pause« and the distance between the beginnings of two consecutive pulses with "pulse period" :designated.

Es sind Impulsregler mit Längenmodulation bekannt, die mit konstanter, einstellbarer Impulsperiode arbeiten. Diese Impulsregler haben für den Fall, daß die Impulslänge .in die Größe der Impulsperiode kommt, den Nachteil, daß sie bei Verwendung in einem Regelkreis leicht instabil werden.Pulse regulators with length modulation are known which operate with constant, adjustable pulse period. These pulse regulators have in the event that the pulse length .in the size of the pulse period, the disadvantage that it is Use in a control loop can easily become unstable.

Die Erfindung richtet sich auf einen Impulsregler mit Impulslängenmodulation, bei dem dieser Nachteil dadurch vermieden -ist, daß er gemäß der Erfindung unabhängig von der Impulslänge mit einer konstanten einstellbaren Impulspause arbeitet. Ein derartiger Impulsregler behält .auch dann, wenn die Impulslänge etwa die gleiche Größe wie die Impulsperiode hat, seine ursprüngliche Stabilität bei.The invention is directed to a pulse regulator with pulse length modulation, in which this disadvantage is avoided in that it is independent according to the invention of the pulse length works with a constant adjustable pulse pause. A Such a pulse controller retains .also when the pulse length is about the same Size as the pulse period has its original stability.

Eine praktische Ausführungsform des erfindungsgemäßen Impulsreglers kann in der Weise ausgebildet sein, d.aß er zwei Zeitglieder enthält, von denen das eine für die Impulsdauer und das andere für die Impulslänge vorgesehen ist.A practical embodiment of the pulse regulator according to the invention can be designed in such a way that it contains two timing elements, one of which one for the pulse duration and the other for the pulse length.

Diese Zeitglieder betätigen sich wechselseitig, indem jeweils das eine nach Ablauf der an ihm eingestellten Zeit das andere einschaltet.These timers operate alternately by adding the one switches on the other after the set time has elapsed.

Die Zeitglieder können beispielsweise aus mechanischen Hemmwerken bestehen, die ähnlich wie Verschlüsse von Photoapparaten ausgebildet sind. Ebenso ist die Verwendung von anderen bekannten Zeitgliedern, wie von pneumatisch wirkenden Speicherwiderstandsgliedern oder elektrisch arbeitenden Kondensator-Widerstandsgliedern möglich. Insbesondere ist die bekannte Multivibratorschaltung für die Darstellung der beiden Zeitglieder in dem erfindungsgemäßen Impulsregler geeignet.The timing elements can, for example, consist of mechanical escapement mechanisms exist, which are designed similar to the closures of cameras. as well is the use of other known timers, such as pneumatically operated Storage resistance elements or electrically operating capacitor resistance elements possible. In particular, the well-known multivibrator circuit is useful for the display of the two timing elements in the pulse regulator according to the invention.
