  1. Flight Control Dynamics & UAVs

  2. Outline • Their history • Basic flight controls • Roll • Pitch • Their benefits • Where they are headed • Questions

  3. Their History: • The first UAV was developed in 1917 – it was a crude motorized bomb • They were developed for risky military operations • They are still mainly used in the military, but they are also used in weather fields

  4. Flight Controls • Several systems to be controlled • Many of them are simple, or can be simplified for a model • Most on different platforms

  5. Roll – Actual Block Diagram

  6. Roll – Model Block Diagram From this ζ turns out to be 0.45 and ωn is 1.34. Gain = 0.16

  7. Pitch de=0.2;A=[-0.313 56.7 0; -0.0139 -0.426 0; 0 56.7 0]; B=[0.232; 0.0203; 0]; C=[0 0 1]; D=[0]; step(A,B*de,C,D)

  8. Pitch – with feedback & PID controller de=0.2; Kp=2.9; Kd=3.5; Ki=3; numo=[1.151 0.1774]; deno=[1 0.739 0.921 0]; numpid=[Kd Kp Ki]; denpid=[1 0]; num1=conv(numo,numpid); den1=conv(deno,denpid); [numc,denc] = cloop(num1,den1); t=0:0.01:10; step (de*numc,denc,t)

  9. Benefits of UAVs • Safety • No pilot to be shot down • Can fly into hurricanes or at low altitudes over the ocean • Little damage when they crash due to their light weight • Affordability • 40 – 70% less than equivalent manned aircraft • Advancement of science and controls

  10. The future of UAVs • Continued use in military and weather applications • Cargo and supplies transportation (5-8) • Interplanetary exploration (10-15) • Personal carrier (?) • Civilian transportation (?)
