Controls Chapter 1 Flashcards
(33 cards)
Actuator
A device employed by the control system to alter or adjust the environment.
Analysis
The process of examining a system in order to gain a better understanding, provide insight, and find directions for improvement.
Automation
The control of a process by automatic means
Closed-loop feedback control system
A system that uses a measurement of the output and compares it with the desired output to control the process
Complexity of design
The intricate pattern of interwoven
parts and knowledge required.
Control system
An interconnection of components forming a system configuration that will provide a desired response.
Control system engineering
An engineering discipline that
focuses on the modeling of a wide assortment of physical systems and using those models to design controllers that will cause the closed-loop systems to
possess desired performance characteristics.
Design
The process of conceiving or inventing the forms, parts, and details of a system to achieve a specified purpose
Design gap
A gap between the complex physical system and the design model intrinsic to the progression from the initial concept to the final product.
Disturbance
An unwanted input signal that affects the
output signal.
Embedded control
Feedback control system that employs on-board special-purpose digital computers as integral components of the feedback loop.
Engineering design
The process of designing a technical
system.
Feedback signal
A measure of the output of the system
used for feedback to control the system.
Flyball governor
A mechanical device for controlling the
speed of a steam engine
Hybrid fuel automobile
An automobile that uses a conventional internal combustion engine in combination with an energy storage device to provide a propulsion.
Internet of Things (IoT)
Network of physical objects
embedded with electronics, software, sensors, and connectivity
Measurement noise
An unwanted input signal that affects the measured output signal.
Mechatronics
The synergistic integration of mechanical,
electrical, and computer systems.
Multiloop feedback control system
A feedback control system with more than one feedback control loop
Multivariable control system
A system with more than one input variable or more than one output variable
Negative feedback
An output signal fed back so that it
subtracts from the input signal.
Open-loop control system
A system that uses a device to
control the process without using feedback. Thus, the output has no effect upon the signal to the process.
Optimization
The adjustment of the parameters to achieve the most favorable or advantageous design.
Positive feedback
An output signal fed back so that it
adds to the input signal.
