Discrete

R2026b
Blöcke zur Modellierung zeitdiskreter Systeme, die mit festen Abtastraten aktualisiert werden, z. B. Delay, Discrete-Time Integrator und Discrete Filter

Verwenden Sie Blöcke aus der Bibliothek „Discrete“, um Systeme zu modellieren, die sich nicht kontinuierlich, sondern in festen Abtastintervallen aktualisieren. Sie können Einheitsverzögerungen, zeitdiskrete Integratoren, digitale Filter und Zustandsraummodelle implementieren, die in festgelegten Abtastintervallen ausgeführt werden. Näheres zu Systemen, die sich zeitlich kontinuierlich verändern, finden Sie in der Kontinuierlich-Bibliothek.

Näheres zum Hinzufügen von Blöcken aus dieser Bibliothek zu Ihrem Modell finden Sie unter Add Blocks to Models.
