Reglerentwurf
Zum Entwickeln und Analysieren von in der Simulink-Umgebung modellierten Regelungssystemen empfiehlt sich die Software Simulink Control Design.
Simulink Control Design erweitert Simulink und ermöglicht es Ihnen, Betriebspunkte zu finden und exakte Linearisierungen von Simulink-Modellen bei verschiedenen Betriebsbedingungen zu berechnen. Simulink Control Design bietet zudem Tools, mit denen Sie simulationsbasierte Frequenzgänge berechnen können, ohne Ihr Modell zu verändern.
Simulink Control Design bietet mehrere Ansätze zur Anpassung von Simulink-Blöcken, wie z. B. Transferfunktion und PID-Controller-Blöcke. Mithilfe dieser Verfahren und Tools können Sie:
Rückkopplungsschleifen, die die Blöcke PID-Controller oder PID-Controller (2DOF) enthalten, automatisch anpassen.
SISO-Rückkopplungsschleifen mit allen anpassbaren Simulink-Blöcken grafisch oder automatisch abstimmen.
Simulink-Modelle von Regelungssystemen mit beliebiger Struktur anpassen, um übergeordnete Entwurfsziele wie Referenzverfolgung, Störungsunterdrückung und Stabilitätsmargen zu erfüllen.
