    כיול שגיאת הצבה של סנסורים הוא משימה חשובה בכל יישום בו יש ריבוי של חיישנים כמו עקיבה מרובת מכ”מים  אחרי מטרות אוויריות. במקרים רבים הכיול מתבצע בעזרת רפרנס מדויק אליו ניתן להשוות פלט  של אלגוריתם כלשהו ולקזז את שגיאות ההצבה על סמך הפער ביחס לאותו הרפרנס.  בהיעדר רפרנס כזה נרצה לבצע כיול אבסולוטי על סמך המידע  של הסנסורים הלא מכוילים בלבד. בפרויקט זה נכיר ונממש מספר . שיטות לכיול שגיאת...

  • C04- בקרה אינרציאלית של גימבל תלת צירי

    יש לבצע בקרה לגימבל תלת צירי בעזרת משוב ממדידים אנרציאלים. הגימבל מאפשר קבלת פקודות זווית אנאלוגיות לשלשת המנועים וקבלת תפוקות משלושה   ג’ירוסקופים , שלושה  אנקודרים ושלושה מדי תאוצה לצורך ביצוע סגירת חוגים בתוכנה בזמן אמיתי. מטרת הפרוייקט הינה סגירת חוגי בקרת מהירות ומצב יחסיים ואינרציאליים על כל גימבל בנפרד. החוגים יאפשרו  מתן פקודות עקיבה חיצוניים על כל גימבל. שלבי עבודה: פיתוח מודל סימולציה מקורב של המערכת על בסיס נתוני המערכת ותוצאות מדידות ספקטראליות וזמניות...

  • C03- פיתוח מערכת בקרת סיבוב מנועי רחפן להשקטת רעשים אקוסטיים

    מטרת הפרויקט הינה להשקיט רעשים אקוסטיים של רחפנים. הפרויקט יבוצע בעזרת בקרה ספרתית על פרשי פאזה זוויתיים  של 4 מנועים המסובבים מדחפים. הפרויקט מבוסס על מחקר ניסויי המראה, שהשקטת רעשים אקוסטיים של רחפן אפשרית על ידי בקרה על תדר הסיבובים והפרשי מופע של זווית הלהבים שלו. עוצמת הרעשים האקוסטיים נמדדת בעזרת חיישנים מתאימים המצויים במערכת המבוקרת.

  • C02- Control Design and Analysis of Servo-Systems with Friction and Backlash

    Friction and Backlash are present in almost all electro-mechanical systems: Servo system drives (linear/rotational) , Single/double gimbals systems, Robotic manipulators, Inertial/optical stabilized platforms. Friction control problems: –     causes rapid disturbance changes when the velocity is reversed. -performance degradation: tracking errors, limit cycles, hunting -wear and damage to components – Backlash control problems: – decreased steady-state accuracy; – tracking errors, limit cycles   This research will be focused on the modern control design approaches...
