Gc(s)G(s) = K / ((1 + s/4)(1 + s)(1 + s/20)(1 + s/80))
where K = 10. Use MATLAB to obtain the Bode diagram of this system.
L(s) = Gc(s)G(s) = K / (s(s + 8)(s + 12))
G(s) = K / (s(s/2 + 1)(s/6 + 1))
We want to have a velocity error constant of Kv = 20. We also want to have a phase margin of approximately 45 degrees and a closed-loop bandwidth greater than ω = 4 rad/s. Use two identical cascaded phase-lead networks to compensate the system.
G(z) = K(z + 0.5) / (z(z – 1))
