Question: A robotic arm has a joint-control loop transfer function L(s) = Ge(s)G(s) = 100(s + 0.1) s(s + 1)(s + 10)* Show that the frequency

A robotic arm has a joint-control loop transfer function

L(s) = Ge(s)G(s) = 100(s + 0.1) s(s + 1)(s + 10)*

L(s) = Ge(s)G(s) = 100(s + 0.1) s(s + 1)(s + 10)* Show that the frequency equals 11.7 rad/s when the phase angle of L(jw) is -135. Find the magnitude of L(jw) at w 11.7 rad/s.
