According to W.R. ASHBY: “…because a change of parameter value changes the field, and because a system's stability depends on its field, a change'' of parameter value will in general change a system's stability in some way” (1950, p.77).
- “Change of parameter value may result in any change which can be produced by the substitution of one field for another: stable systems may become unstable, states of equilibrium may be moved, single states of equilibrium may become multiple, states of equilibrium may become cycles, and so on…
- “…the relationship… is reciprocal: in a state-determined system, a change of stability can only be due to a change of value of a parameter, and change of value of a parameter causes a change in stability” (Ibid.p.78).
