Principles of Engineering

 

Control Systems

Controls

Automation - A machine or system that operates with minimal human control: using automated machines as control for production.

Interface - The interconnection between components or systems.

Robotics - The specialized field of engineering and computer science that deals with the design and application of robots.

Photo-resistor - A device that changes resistance according to light intensity.

  • Inputs:  E1, E2, E3, etc.  Switches, Phototransistors
  • Outputs:  M1, M2, M3, etc.  Motors, Lamps, Buzzers, Electro Magnets
  • Analog Values:  EX & EY - will give you a reading of a range of values
  • Function Blocks:

Outputs

Inputs

Input Devices

  • Open Loop - A control system where there is no feedback circuitry.

 

  • Closed Loop - The output of a process is constantly monitored and the input adjusted according to feedback provided by sensors.
