Transfer function stability
is the transfer function of the system (8.2); the function Gxu(s) = (sI−A)−1B is the transfer function from input to state. Note that this latter transfer function is actually a vector of ntransfer functions (one for each state). Using transfer functions the response of the system (8.2) to an exponential input is thus y(t) = CeAt x(0)−(sI ...

To check the stability of a transfer function, we can analyze the real parts of the transfer function's poles. If all the real parts of the poles are negative, the transfer function is considered stable. If there are repeated poles on imaginary axis and no poles of right hand plane, the transfer function is considered marginally stable.Transfer Function Gain and Relative Stability In a linear control stable system, the transfer function gain can be utilized for defining its relative stability.

Namely, rules of thumb are that your bandwidth should be below the RHP zeros and your bandwidth should be above the RHP poles. But those contradict each other due to the locations of the RHP pole and zero of your system.The term "transfer function" is also used in the frequency domain analysis of systems using transform methods such as the Laplace transform; here it means the amplitude of the output as a function of the frequency of the input signal.
