railway DFCCIL Junior Executive 2023 (CBT 1 & CBT 2) Mock Test Control Systems Controllers and Compensators Compensators
The transfer function of the lead compensator is:
1
Gc(s) = \(\rm\frac{1}{\beta} \frac{s+\frac{1}{T}}{s+\frac{1}{\beta T}}\) where β < 1
2
Gc(s) = \(\rm\frac{1}{\beta} \frac{s+\frac{1}{T}}{s+\frac{1}{\beta T}}\) where β > 1
3
Gc(s) = \(\rm\frac{1}{\beta} \frac{s−\frac{1}{T}}{s−\frac{1}{\beta T}}\) where β > 1
4
Gc(s) = \(\rm\frac{1}{\beta} \frac{s−\frac{1}{T}}{s−\frac{1}{\beta T}}\) where β < 1
