Hallo,
nun bin ich wieder etwas weiter, nachdem ich die Fitness-Funktion debuggt habe. Jetzt kommen richtige Werte raus, vorher nicht! Außerdem habe ich jetzt noch eine Art Startup Prozedur eingebaut, d.h. erst schwingt sich der Quadro ein und dann wird die Fitness von den Startparametern bestimmt.
Hier der Code:
Jetzt muss ich nur noch die Simulated-Annealing Parameter richtig einstellen xD Aber vom Prinzip her funktionierts.Code:$regfile = "m328pdef.dat" $crystal = 16000000 $framesize = 200 $hwstack = 200

Evtl. werd ich das ganze morgen mal, mit kleiner Temperatur, im richtigen Flug (also ohne Teststand) probieren... Mal sehen.

EDIT:
Um das ganze besser testen zu können, verwende ich nicht die Gyro-werte für die Fitness-Berechnung, sondern den Fehler aus Gyro-wert minus RC-wert. Somit kann auch mit einbezogen werden, wie gut die Parameter dem Piloten folgen. Was haltet ihr davon?
