Objectives This course introduces the linear feedback control systems.

This is a multidisciplinary course equally applicable to electrical, chemical, mechanical, aeronautical engineering.

In this course the components of a linear feedback control system are introduced.

The design methodology, in order to achieve desired response with proper specs, is presented.

Stability and design issues are discussed. The concepts covered in the lectures will be elaborated using

computer simulations on MATLAB and SIMULINK as well as experiments in the lab.

End Product The student shall be able to understand the

difference between open loop and closed loop systems along with their advantages and disadvantages.

By the end of this course the student should be able to analyze a control system with respect to desired response, performance and stability issues.

The student should be able to develop block oriented design approach for any discipline of engineering.

IntroductionControl systems are an integral part of modern

society. Numerous applications are all around us: Household appliances, temperature-control system, robotic systems , traffic control systems, chemical process systems. Control engineers are concerned with controlling segments of their environment, often called systems, to provide useful economic products for society.

What is a control system? A control system is an interconnection of

components forming a system configuration that will provide a desired system response.

Cause-effect relationship Each component is described by a cause-

effect relation. Therefore a component or process to be controlled can be represented by a block

The input- output relation represents the cause-and-effect relationship of the process
