Non minimum phase system

Unstable zeros are indicators of some "counter-acting dynamics" in the system. You can find nonminimum-phase models in description of lateral and directional dynamics of an aircraft. Tilting a standard aircraft to the right will eventually induce moments that move it back to the level flight.

LHS zeros: Furnace fired with cool (non-preheated) fuel. Step change in fuel initially depresses the furnace temperature, finally rising to to new higher steady-state value.

Hi Danielle,

Distillation columns. The linearised transfer function, G(s) invariably will have RHP zeros, that invert into RHP poles for the model.

PS

Where can I find a description of that model?

Thanks

In every textbook on flight dynamics.
