Flux Pavillion - Digital Controller

Why a Z-domain controller may not be realizable when it is converted to difference equations ?

Some digital controllers designed using pole placement method may not be realizable. Explain Why a Z-domain controller may not be realizable when it is converted to difference equations for implementation ?

If the control response is to be stable, the region of convergence must contain the unit circle. If all the poles are outside the unit circle, then to be stable the impulse response must be anticausal, meaning that the entirety of the response depends on future events. If the poles are on both sides of the unit circle, then the response is entirely two-sided, meaning that it depends on both past and future values. Digital control systems must be causal except under certain specific circumstances.

This may not be what you're looking for, but I hope it's helpful.
