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
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 (ωgc) and phase crossover frequency (ωpc) will be related as-
