CP6.5 A “paper-pilot” model is sometimes utilized in air

craft control design and analysis to represent the pilot in the loop. A block diagram of an aircraft with a pilot

“in the loop” is shown in Figure CP6.5. The variable

τ represents the pilot’s time delay. Assume that we have a fast pilot with τ = 0.1 and = 1. Develop an m-file to obtain the region of stability for τ1 and τ2 , changing in the range of 0 to 5. Show step responses for two points: one inside and one outside of this region.
