The polar plot of given transfer function
The open loop transfer function is given below
The number of anticlockwise encirclements about (–1, 0) point for the system to be stable_______.
for a closed loop system to be stable, the nyquist plot of G(s)H(s) must encircle the point (-1, j0) as many times as the number of
The closed loop frequency response, |M(jω)| versus frequency of a second order system is shown below:
The value of the maximum overshoot (Mp) in percent and natural frequency (ωn) of the system for unit step input are respectively.
Consider the closed loop transfer function
The magnitude plot |T(jω)| versus (ω/ωn) of the system for different values of damping ratio (ξ) is shown below.
Which of the following orders of damping ratios is correct?
A unit step input is applied to a unity feedback control system having open loop transfer function,
The specifications are such that the maximum overshoot is 20% and resonant frequency is ωr = 6 rad/sec. The values of K and T are
