` `
**Introduction:**

The faculty supervisor for this course
is Dr. Beale,
Room 257, Science and Technology II, 993-1596. His office hours are shown
on his homepage. The GTA will be responsible for providing assistance to
the students during the lab and during his/her office hours. The GTA will
also be responsible for all grading in the lab, and will set standards for
the grading. The weighting of the various experiments will be based on
the number of weeks assigned to the experiments.

` `
**Objectives:**

The objective of this laboratory is to enable
the students to strengthen their understanding of the design and analysis
of control systems through practical exercises. This will be accomplished
by using modern software resources to analyze and simulate the performance
of realistic system models and to design control systems to satisfy
various performance specifications.

` `
**Overview:**

The control systems laboratory consists of three separate units. Each
unit consists of several experiments. Unit A involves analysis and
controller design for a fairly simple system model. Unit B involves the
design and analysis for a much more realistic system, involving
disturbances and varying parameters. Unit C involves compensator design
for a system involving pure time delay. Students in the lab will be
divided into groups of two students each. Students will document each
experiment with a description of their procedures, results of their
analysis or design, and plots as appropriate. The reports for the various
experiments within a particular set will be turned in to the GTA at one
time when the set is completed.

This set of experiments is intended to provide students with a review of standard control system design techniques for a fairly simple single-block system. Gain compensation is used initially, and then dynamic compensators, such as phase lead or phase lag, are used to satisfy certain performance requirements. Requirements are given in both the time domain and frequency domain.

` `
**Unit B -- 5 weeks:**

This set of experiments is intended to introduce students to the design of
control systems for realistic applications. Tension control is an
important function in film finishing machines. A movable dancer roll is
used to maintain constant tension in the film as it is pulled through the
machine. To function properly, the dancer roll must not be allowed to
exceed its maximum allowable position limits. The position of the dancer
roll must be kept near its center of travel in the face of disturbances
acting on the system. These experiments will involve the design of a
control system which will satisfy certain performance objectives in the
face of varying parameter values and external disturbances.

Unit B.3

` `
**Unit C -- 4 weeks:**

The transfer function which is to be used in this set of experiments
arises during the study of control system design of first-order systems
which have pure time delays in them and the purpose of the controller is
to work with different values of time delay. This turns out to be
equivalent to another control problem, namely designing a compensator
which works with a particular transfer function representing a
"fictitious" system. The system to be controlled in this set of
experiments is the fictitious system, and part of the set will involve
investigating the dependence of the value of the time delay on the
characteristics of the compensator.
