DFCCIL EE/EC Control Systems QUIZ - 4

The phase cross-over frequency of the transfer function  in Hz is.

Open loop transfer function of unity feedback system is . For input sin(ωt), At ω₁ frequency (rad/sec), steady state response shows the peak. The value of ω₁ is ________rad/sec.

A unity feedback control system is characterized by the open-loop transfer function

The value of k for which the system oscillates at 2 rad/s is_____

A system with input x(t) and output y(t) is described by the following differential equation:

The system is said to be

When the system will be stable?

For a closed loop system to be stable the gain crossover frequency (ω_gc) and phase crossover frequency (ω_pc) will be related as-
