You didn't say how much "resolution" you needed.
If you use a standard NTSC camera, there are all kinds of capture
programs and HW that will convert the video into computer images for you
to study.
But assuming you'd like all you can get. Take a standard vidicon camera
(not a CCD) and rotate it 90 degress so that the horizontal lines are
intercepted by the pattern of the beam (assuming it's horizontally
mounted).
Even though the camera may have 200-400 lines of resolution (this is the
ability to see black and white vertical bars) the "phase resolution will
be equivalent to over 1200 lines! And you will almost get complete
linear resolution with very little quantization.
Even though the camera system does not focus perfectly, or resolve small
edges well, the *placement* of that edge is quite good. All you need to
do is define where in the transition voltage is what you define as edge.
Some gotcha's will be in the uality of the illumination of the object to
make certain that it doesn't change much during deflection. And
linearity of the lensing, but if you make the small beam deflection the
whole field of view, this shouldn't be a problem.
If you feel brave; you can use a linear CCD array, like the Toshiba's
103, add a lense, and use a scope to count the pixels of beam
deflection. Several linear arrays come in 2000-3000 pixels and are
quite easy to operate with some simple electronics. Since the output of
the CCD will not be an abrupt transition, you can interpolate between
pixels to define the edge and increase your resolution, too.

There are matlab functions that will transform a transfer function from
discrete to continuous or vice versa. I don't think there is any way to
get around changing both transfer functions to the same domain. If you
go to the z-plane use dbode.

Dear John, I have read your Web page with great interest,
particularly the explanations about the PID controller.
I have two topics that I would like to run by you for comment.
Topic 1
********
I see you, like many other authors and control system
manufacturers, chose to not include the derivative filter
in the equation or block diagram describing the PID controller.
However, I see that you definitely included it in your
PID pseudo-code. As I am sure you know, the derivative filter
is very important to the operation of the derivative term
since without it, the result would be a very overactive
pre-act(tm) effect. The common practice is to set this
derivative filter time constant to a proportion of the
derivative constant, i.e. derivTimeConst = theta x D,
where theta is 0.05 to 0.4 (0.1 or 0.2 most common).
I would be very interested to hear your comments about
this "fourth term" and if you have utilised the ability
to adjust this parameter in some of the recent PID
implementations in some DCSs.
I have found that the reason that why many PIDs have D=0 is that
the derivative is over-active when it is introduced and the reason
why it is overactive is that theta is too small (say 0.1).
Increasing theta to say 0.4 will allow the derivative
to be set correctly without the excessive noise amplification.
It is often the case that you only require a small amount of phase
boost from your derivative, but you cannot achieve this by
simply making D smaller. Any comments you would care to make
on this topic would be appreciated.
*****************************************************************
Topic 2
*******
On a related topic, I have visiting student who is currently doing
some research on the various forms of PID algorithms (Ideal,
Series and Parallel) and their effect on Ziegler-Nichols
tuning rules. I am led to believe that Ziegler and Nichols
used a Taylor Fulscope three term pneumatic controller for their
experiments. Would you be able to confirm that this was the case?
If so, a collegue of mine has carried out a bench test on this
particular controller and has found a theta of 0.2 by experimentation.
Being a pneumatic controller, it is likely that the form of algorithm
is the series type. If this is the case, the Z-N rules are,
in principle, only relevant to this form of controller. If you
apply the Z-N constant to a PID that has, say, an Ideal form with
a theta of 0.1, the you could get quite different results to
what you expect. We are working on getting translations between
the different forms with the inclusion of the effect of theta.
If the controller was a Taylor fulscope three term, could you
please advise where I can get a data sheet from so that I can
confirm what form of PID it is. I have been told that Taylor
was one of the first companies to introduce the pneumatic
three term controller and this was in the early forties around
the time of the Z-N experiments.

CICS AUTOMATION was formed in 1994, initially to commercialise advanced
industrial control products developed at the Centre for Industrial
Control
Science, The University of Newcastle. The company has expanded and now
offers complete advanced solutions to industrial control engineering
problems, through its range of products and services.
THE CENTRE FOR INTEGRATED DYNAMICS AND CONTROL (CIDAC) is a recently
awarded Special Research Centre to The University of Newcastle. It
incorporates the former Centre for Industrial Control Science. CIDAC
will
involve research encompassing key open problems in the areas of
nonlinear
dynamics, multivariable control, discrete even dynamics, hybrid systems,
autonomous control and adaptive systems. A distinguishing feature of
the
Centre will be the amalgamation of the study of theoretical issues
together
with their application to problems of industrial importance.
THE VENUE The course will be held at the University of Newcastle campus
within the Faculty of Engineering. The Campus is situated in a bushland
setting approximately 15 minutes by car from the City Centre.
THE PRESENTERS Professor Graham Goodwin, Director of CIDAC and
Professor
of Electrical and Computer Engineering; A.Prof Rick Middleton, Assoc.
Director of CIDAC; Dr Brett Ninness, Lecturer, Dept of Electrical &
Computer Engineering, from the University of Newcastle, and Dr Sam
Crisafulli, Engineering Manager of CICS Automation.
ASSUMED KNOWLEDGE The course assumes a basic understanding of systems
and
signals theory at a level typified by undergraduate engineering and
science
courses. A review of this material will be presented to refresh those
who
might be a little rusty!
COURSE FEE The fee for the course is A$890 and will be held on 20 & 21
February 1997 at the University of Newcastle. The fee includes printed

The dynamics of steam turbines are generally governed by the one
dominant time constant derived from the rotating element inertia. The
design of controls for such systems is focussed on maintaining the
system order at near to one, by reducing other time constants
(principally the slew rate of the final actuator) to values well below
that of the inertial dynamics. Reason for doing this is that a (near)
first order system can have a high gain controller on it, with the
attendant benefits of fast response and tight setpoint tracking. This
arrangement also has benefits for parallell operation, where
controlled droop is used to balance the system.
Most DCS controllers sample at between 1/4 and 1 second per scan. For
anything other than a very small turbine/driven device combination,
this sampling should be OK. It will show as a degradation to
achievable control _if_ the final element is fast. If the driven
device is not parallelled with others (eg. altermators on a bus), PID
should be OK, providing somewhat lower quality in speed control is
acceptable. Worth a go if it's going to save a significant amount ....
but make sure the normal independent protective systems are in place
:-)
