PITHAWALA COLLEGE OF ENGINEERING AND TECHNOLOGY PREPARED BY: TAILOR DIGEN K. 160093111016 SARANG SACHIN A. 160093111015 PATEL HARISH S. 160093111012 AKHIANIA PRATIK B. 160093111001 SUBJECT: Control system engineering TOPIC: Introduction to Control System BRANCH: Electronics and Communication GROUP: G1A_5
- 2. Context: • Introduction • History • Examples of control system • Engineering design • Mechatronic system • Future evolution of control system
- 3. Introduction: • System: An interconnection of elements and devices for a desired purpose. • Control System: the control system is an interconnection of components which provide desired output • Process: The device, plant, or system under control. The input and output relationship represents the cause-and- effect relationship of the process.
- 4. • Open-Loop Control Systems: The system in which output has no effect of feedback then it is known as open loop control system. Example: washing machine, hair drier INPUT OUTPUT • Closed-Loop Control Systems: The system in which output has effect of feedback then it is known as close loop control system Example: A.C ,automatic Iron INPUT OUTPUT CONTROLLER PLANT CONTROL ELEMENT FEEDBACK ELEMENT PLANT
- 5. History: • Greece (BC) – Float regulator mechanism • Holland (16th Century)– Temperature regulator Watt’s Flyball Governor(18th century)
- 6. Water-level float regulator
- 7. 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.
- 8. Examples of Modern Control Systems: CONTROL DEVICE SENSOR ACTUATOR PLANT MEASURED OUTPUT FEEDBACK + - A negative feedback block diagram depicting a basic close loop control system. The control device is often called a ”controller”. INPUT OUTPUT
- 9. Car control system: (a) Automobile steering control system. (b) The driver uses the difference between the actual and the desired direction of travel to generate a controlled adjustment of the steering wheel. (c) Typical direction-of-travel response.
- 10. COMPUTER SENSOR ACTUATOR PLANT + - OUTPUT Computer control system INPUT
- 11. Automatic boiler control system: Coordinated control system for boiler generator
- 12. A three axis control system for inspecting individual semiconductor wafers with high Sensitive camera
- 13. Engineering design: If the performance meets the specification then finalize the design If the performance does not meets the Specification check the configuration and actuator
- 15. Design Example of mechatronic

- 17. Future evolution of control system: The MIT dextrous robotic hand: A dextrous robotic hand having 18 degrees of freedom, Developed as a research tool by the centre of engineering design at the university of Utah And artificial intelligence laboratory at MIT. It is controlled by five Motorola 68000 µp And actuated by 36 high performance electro pneumatic actuators via high strength Polymeric tendons. The hand has three fingers and a thumb.it uses touch sensors and Tendons for controls
- 18. A laboratory robot used for sample preparation. The robot manipulates small objects, Such as test tubes, and probes in out of tight places at relatively high speed.
