Actual Plant and Transfer Functions of Non-minimum Phase System

We have few transfer function of non minimum phase system. We want to know that their characteristics with real plants. (related to which physical system)

plant 1: -0.5 (s-0.1)/(s(s+1)^2)

plant 2: 0.5 (s-0.1)^2/(s(s+1)^2)

plant 3: -0.5 (s-0.1)/(s+1)^3

plant 4: 0.5 (s-0.1)/(s+1)^3

plant 5: (-s+3)/((s+1)(s+5))

plant 6: (s^2-10s+27)/(s+1)^3
Quote: Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality. Nikola Tesla (1856 - 1943).

When at University I had a flair for studying theory and trying to configure it into real systems - just occasionally it did not work.
Life's experiences tell us sometimes not to bother trying.

Many years ago I had a P&ID function that just would not work. Being on site I had to do something radical - and that was to throw out the P&ID and use my own Algorithm, which was so successful I used it in other schemes.
indeed, you have to understand the process first, then sort out the controls. More than equations are involved in many cases.
