Multiloop stability criteria
Hi hacksaw, In integrated electronics/circuit work, the model/transfer function is always known. Do you have an example where even though the individual loops are stable but the overall MIMO system is unstable? Thanks- Deba1

Multiloop stability criteria
Hi hacksaw, Thanks for the response. After a quick review of relative gain array(RGA), it seems it looks at the steady state gains, and one needs to use that information to tune the loop. What happens if there are frequency dependent blocks are present, like integrators, differentiators, or any...- Deba1

Multiloop stability criteria
Hi, In many textbooks, the Nyquist criteria is used for analyzing the stability for closed loop systems. But they are mostly single input single output(SISO) systems. But there are many systems which have multiple loops, or in general multiple input multiple output(MIMO) systems. For example...- Deba1
