Stability analysis of
closed loop systems
Considerations
Control systems
linear
invariant in time
in discrete time
one input one output
Conditions and important things
Unstable
Poles outside the unit

Critically stable
Poles in the unit
circle
Stable
Poles within the unit circle
Zeros
Closed-loop zeros do
not affect stability
Systems with closed loop pulse transfer function & characteristic equation
Jury stability test
Reveals the existence of any unstable roots. It does not give the location.
General Form of the

P (z) coefficients in order of
rising powers
Coefficients of P (z) in order
of descending powers
