Feedback Mechanisms: Overview Flashcards
What is the starting point of a feedback mechanism where data or stimuli are introduced?
Input.
What part of a feedback mechanism processes the input to produce an output?
Process or system.
What is the result or outcome produced by the system after processing the input?
Output.
What part of a feedback mechanism returns information about the system’s output to adjust further actions?
Feedback loop.
What component compares the output to a desired set point and adjusts the process accordingly?
Controller or comparator.
What is positive feedback?
A feedback that amplifies changes or deviations from the norm, leading to growth or intensification.
What is negative feedback?
A feedback that works to maintain stability by reducing deviations from a set point.
What is a set point in a feedback mechanism?
The desired or optimal value a system aims to maintain or achieve.
What is the error signal in a feedback mechanism?
The difference between the actual output and the desired set point.
What is delay in a feedback mechanism?
The time it takes for the feedback to influence the system’s actions.
How did feedback mechanisms evolve in biological systems?
They evolved from primitive systems to highly sophisticated mechanisms regulating biological functions.
How did mechanical feedback systems emerge during the Industrial Revolution?
Mechanical systems like steam engines used simple governors to regulate speed based on output.
What role did cybernetics play in understanding feedback mechanisms?
Cybernetics formalized feedback systems in biological and machine systems, leading to adaptive control theory.
How have feedback loops been applied in economics?
Market feedback systems became prominent in regulating supply and demand through price signals.
How do feedback mechanisms play a role in modern AI systems?
AI systems rely on feedback to refine accuracy, optimize decisions, and adapt to new data.
How might feedback mechanisms be important in autonomous systems in the future?
Autonomous systems like self-driving cars will need to process feedback from complex environments in real time.
What role could biofeedback play in human enhancement?
Biofeedback could allow humans to monitor and adjust physiological functions for health or performance.
How can feedback mechanisms optimize resource use in future smart cities?
Feedback from environmental sensors could optimize energy, traffic, and resource management.
What role might feedback mechanisms play in future governance and social systems?
Feedback mechanisms could allow dynamic, real-time policy adjustments based on public needs.
What is an example of a future autonomous system using feedback mechanisms?
Self-driving cars that use feedback from sensors to adjust speed and direction in real time.
