Question
The block diagram of a conventional feedback controlsystem contains the following transfer functions:G꜀=K꜀(1+1/5s) ,Gᵥ=1 Gₘ=1/(s+1) ,Gₚ=Gd=5e−²ˢ/(10s+1)(a)Plot the Bode diagram for the open-loop transfer function.(b)For what values ofKcis the system stable?(c)If K꜀=0.2, what is the phase margin?(d)What value of K꜀ will result in a gain margin of 1.7?
