Solution:

In a Polar plot, on what parameters is the closed loop transfer function calculated?

Gain margin and phase margin of the closed loop transfer function

Gain margin and phase margin of the open loop transfer function

Solution:

Why do control systems with negative feedback often face problems of instability?

Due to the lack of knowledge about the subsystems' dynamic equations

Due to systems having a large phase angle at higher frequencies

Due to components having non-linearities

Due to involvement of approximations in the mathematical equations
