Optimierung, Analyse und Validierung

Optimieren von Regelungssystemparametern und Analysieren der Ergebnisse über die Befehlszeile

Nachdem Ihr Modell zur Optimierung eingerichtet ist, passt der Befehl systune die optimierbaren Koeffizienten an Ihre Entwurfsanforderungen an. Zur Validierung des Ergebnisses prüfen Sie die Systemantworten und werten Sie aus, inwieweit die Optimierungsziele erreicht wurden. Für ein in Simulink^® modelliertes Regelungssystem schreiben Sie die optimierten Parameterwerte in das Modell zur Validierung gegenüber dem vollständigen nichtlinearen System. Weitere Informationen finden Sie unter Validate Tuned Control System.

Themen

Grundlagen der Optimierung

Tune Control System at the Command Line
After building a tunable control system model and specifying tuning goals, use systune to tune the parameters of your system.
Tuning Multiloop Control Systems
Jointly tune the inner and outer loops of a cascade architecture with systune.
Speed Up Tuning with Parallel Computing Toolbox Software
If you have the Parallel Computing Toolbox™ software installed, you can speed up the tuning of fixed-structure control systems.

Analyse und Validierung

Interpret Numeric Tuning Results
Tuning reports from systune and Control System Tuner give you an overview of how well the tuned control system meets your tuning goals.
Visualize Tuning Goals
Tuning-goal plots let you visualize your design requirements against tuned system responses, to see where and by how much tuning goals are satisfied or violated.
Validate Tuned Control System
When you tune a control system, validate the results by examining system responses with the tuned parameters.
Extract Responses from Tuned MATLAB Model at the Command Line
Analyze responses of a tuned control system by using getIOTransfer and related functions to compute responses between various points in the model.
Validating Results
This example shows how to interpret and validate tuning results from systune.
