Course Syllabus
Course Aim:
•
•
•
•
•
•
•
To develop an understanding of discrete ¬time signals and
systems, along with sampled ¬data signals and systems. This
includes linear, time¬ invariant systems using digital ¬to ¬analog
and analog ¬to ¬digital converters. This includes understanding
how to obtain a mathematical model of a system with such
components.
To understand the essential properties of discrete¬ time systems
including stability, and performance characteristics.
To develop a basic feel for the time-domain and frequency domain
responses for digital systems.
To understand the essential properties of discrete¬ time systems
including stability, and performance characteristics.
To learn how to design a digital controller to meet time-domain
specifications. These specifications include settling time,
overshoot, steady state error, and maximum control effort.
Design of a digital control system using computer aided tools
To provide the students an opportunity to apply the knowledge of
above material in a practical (project) experience

Course Syllabus
Materials Covered:
• Introduction: The need for a theoretical background, naturally
discrete systems, a comparison of discrete and continuous
systems, the design process
• Sampling and reconstruction of signals: S/H circuit, A/D, and D/A
conversions, digital sensors.
• Review of the z-transform and its properties, modified Z-transform.
• Transfer Functions, Block Diagrams, and SFG for digital control
systems.
• State-Variable Technique applied to digital control systems.
• Controllability, Observability, and Stability.
• Time-Domain and Z-Domain Analysis, comparison between
continuous-data and sampled-data system responses are made,
steady-state analysis and root locus.
• Frequency-Domain Analysis of digital control systems (Nyquist
criterion, Bode plot).
• Design of Discrete-Data Control Systems (PID design, Phase-Lead
and Phase Lag Controllers, Disturbance rejection, Pole-Zero
cancellation, Deadbeat-response design, Pole Placement, state
estimator design).

Computer Usage
Extensive use of MATLAB for computer
aided analysis and simulation. The digital
computers used are IBM PC Pentium
compatible, these are available in the
Department of Electrical Engineering.
Students are required to use these tools and
equipment for special project and homework
development.

What is a System?
System: Block box that takes input signal(s) and converts to
output signal(s).
• Continuous-Time System:

What is a Control System
• A Process that needs to be controlled:
– To achieve a desired output
– By regulating inputs
• A Controller: a mechanism, circuit or algorithm
– Provides required input
– For a desired output

Closed Loop Control
• Open-loop control is ‘blind’ to actual output
• Closed-loop control takes account of actual
output and compares this to desired output
