EE 510: Lumped Systems Theory - Design of Controllers, Lecture notes of Teaching method
The objective of this course is to introduce the students to the basic methods of system theory. Both continuous and discrete time linear systems will be covered. The concepts of stability, controllability and observability are taught. In addition, the design of controllers and observers is discussed.

Outline of the Handout
- Introduction to Control Systems
- Performance Specifications
- Underdamped Second–Order Systems

- Regulators and Servos
- State feedback for DT Systems
- Control of Systems which are not Completely Controllable
- Output Feedback
A control system consisting of interconnected components is
designed to achieve a desired purpose. To understand the purpose
of a control system, it is useful to examine examples of control
systems through the course of history. These early systems
incorporated many of the same ideas of feedback that are in use
today.
Modern control engineering practice includes the use of control design
strategies for improving manufacturing processes, the efficiency of
energy use, advanced automobile control, including rapid transit, among
1. Introduction to Control Systems
Introduction
System – An interconnection of elements and devices for a desired purpose.
Control System – An interconnection of components forming a system
configuration that will provide a desired response.
Process – The device, plant, or system
under control. The input and output
relationship represents the cause-and-
effect relationship of the process.

History
18th Century James Watt’s centrifugal governor for the speed control of a
steam engine.
1920s Minorsky worked on automatic controllers for steering ships.
1930s Nyquist developed a method for analyzing the stability of controlled
systems
1940s Frequency response methods made it possible to design linear closed-
loop control systems
1950s Root-locus method due to Evans was fully developed
1960s State space methods, optimal control, adaptive control and
1980s Learning controls are begun to investigated and developed.
Present and on-going research fields. Recent application of modern control
theory includes such non-engineering systems such as biological, biomedical,
economic and socio-economic systems? ????????
