A is said to control B if, for every disturbing
influence acting on B, A generates
an action that tends strongly to counteract the effect of the disturbing influence on B.(Bjorn’s statement)
Here are some definitions
of control from PCT books and from other sources
and maintenance of a pre-selected perceptual state in the controlling system, through
actions on the environment that also cancel out the effects of disturbances. (Powers)
If a person is to control
something, the person has to be able to affect whatever is to be controlled. (Powers)
producing repeatable consequences by variable actions. (Powers)
Perception tells us of
the current status of whatever it is we are trying to control. (Powers)
To control something is
to act to bring it to a specified condition and then maintain it close to that condition and then ** maintain** that condition even if
unpredictable external forces and changes in environmental properties tend to alter
Regulation and control
are intimately related. (Ashby, Introduction to
Oxford ** Dictionary:**
Control1: the fact of
controlling, or of checking and directing action; domination, command, sway.
Control 2: Restraint, check
Control 3: A method or
means of restraint
Control 4: to call to
Control 5: to overpower;
In most dictionary terms
controlling seems to have a stopping or checking or regulating or dominating meaning
in both the noun and verb forms.
Now reading the main definition
from BCP Control is clearly achieving or maintaining
(in this case a perceptual state).
In the definition provided
by Bjorn it has the normal meaning (ie checking or
stopping, regulating, dominate).
This is a verbal cocoon clearly
the meaning of both controls are not entirely the same thing, that is the inference
levels are different.
They may be subtle differences
but they have enormous consequences for communication of the subtleties of PCT.
There is nothing wrong
with the definition give by Bjorn, but it’s not at
the same inference level as control in PCT.
This is not my interpretation
of the language this is what the language is saying.
