The notion of design trade-offs in
control design had started to present
itself. There was no theory.

Maxwell recognized, but could not
solve the general stability problem

In France, Hermite formulated
and solved the general stability
problem, without recognizing the
application significance.

What is “Control”?
Control is:
• Giving suitable inputs to regulate a system to achieve
some desired control objectives
• Traditional view: Use of feedback to provide stability,
performances, robustness.
• Emerging view:
• Set of tools and techniques to analyze, design
and realize complex systems in presence of
uncertainty
• Combination of dynamics, interconnections
(feedback/feedforward), communications,
computing and software

Solving a control problem?
1. System identification problem
‒ What is the type of mathematical model
(equations) of the system? – black box
identification
‒ What is the parameters of the system?

Solving a Control Problem?
2. Simulating the system
‒ Does the system model match my data?
‒ How does it behave with different inputs?
‒ Simulate with extreme conditions
Simulations can save a lot of time, money, and
even human lives

Solving a Control Problem?
3. Control design problem
‒ How can I get my system to meet my
performance requirements?
‒ How can I automate a process that
currently involve human in the loop?
‒ How can my system operate in a dynamic
and noisy environment?
Realizing the system?

The IEEE Control System Society Mission
The Control Systems Society is dedicated to the advancement of the
theory and practice of systems and control. Founded in 1954, the IEEE
CSS has been at the forefront of control systems theory and technology
for over 65 years. Its focus is to promote scientific, technological, and
educational advancements in the fields of automatic control, decision
making, theory and applications, all over the world. Application areas
include, and not limited to, aerospace systems, automotive systems,
communication networks, cyber-physical systems, manufacturing,
micro/nano systems, power grids, process control, robotics, smart
communities, and systems and synthetic biology.

IFAC (International Federation of Automatic Control)
https://www.ifac-control.org/
Vision
…for IFAC to be the worldwide federation for promoting automatic
control for the benefit of humankind
Mission
…to promote the science and technology of automatic control
through technical meetings,
publications and other means consistent with the goals and values
of IFAC.
Foundations
