  1. Lecture II: SE 201 Introduction to Automation/Control Systems

  2. Objectives • Define the role of an automation/control engineer • Define the fields of related knowledge to automation and control • Define the scope of the career of an automation and control engineer • Grasp definitions and concepts • Examples

  3. Automation/Control Systems Engineers • Automation/Control systems engineers are concerned with understanding and controlling segments of their environment (Systems) to provide useful economic products for society

  4. Effective automation/control require: • Understanding • Modeling • Designing • Testing • Implementation • Monitoring

  5. Automation/Control engineering is based on the foundations of: • Feedback theory • Linear system analysis • Control Engineering Integrates • Network theory • Communication theory • Reliability and maintenance theory • Safety theory

  6. Scope of Automation/control engineering • Not limited • Aeronautical • Chemical • Mechanical • Environmental • Civil • Electrical • Biomedical • …..

  7. Definition 1: • A control system is an interconnection of components forming a system configuration that will provide a desired system response. • Analysis in general involves: • Linear system Theory : Assumes Cause-effect relationship for the components of a system.

  8. Effect Cause Process Output Input Usual Representation • Every component (or process) can be represented by a block • SISO: Single input Single output

  9. Process Actuator Output Desired Output response Usual Representation • SIMO: Single input multi-output • MISO: • MIMO:

  10. Process Actuator Output Desired Output response Open-Loop Control System • An open-loop control system utilizes an actuating device to control the process directly without using feedback.

  11. Open loop system

  12. Comparison Actuator Process Desired Output Output Measurement Close-Loop Feedback Control • A close-loop system uses a measurement of the output and feedback of this signal to compare it with the desired output (reference or command)

  13. History • Watt’s Fly ball governor 1769.
