… To get
any system, you need
special condition involving time delays. When
you do get oscillations, there must be nonlinearities in the
or the result is literally an explosion (which is, I guess, an
expression of a nonlinearity :-).
I see the
possibility for explosion if different parameters are
You have that backwards. The problem of explosion happens when
the systems (not the parameters – they are just numbers) are LINEAR.
Nonlinear system MAY explode, but linear ones that introduce
oscillation WILL explode (as will linear systems that have a loop gain
greater than unity).
And in my earlier message I did mean “literally”, with
a physical bang and burn-up of the system, not a metaphoric one of a
value “going to infinity”.
The rest, later.
