Answer 1

Concept:

Corner frequency:

The point in Bode plot, where slope changes i.e. location of poles & zeros.

Calculation:

From above open loop transfer function we get,

Poles = - 0.5, - 3.03

∴ No of corner frequencies = 2

∴ Given system have corner frequency = 0.5, 3.03

Note:

In general, bode plot will have transfer function in time constant form.

i.e.

where, std. the open-loop transfer function for bode plot;

By comparing;

K = 6.6

& are corner frequencies.
