What defines a linear control system?
Click to flip
A linear control system follows the principle of superposition, meaning its output is directly proportional to its input.
Click to flip
What is a non-linear control system?
Click to flip
A non-linear control system does not follow the principle of superposition, and small changes in input can cause large changes in output.
Click to flip
What is a digital control system?
Click to flip
A digital control system uses digital signals, typically managed by a microcontroller or computer, to control its components.
Click to flip
What is an analog control system?
Click to flip
An analog control system uses continuous signals to control its components, typically involving analog electronics.
Click to flip
What is the advantage of using a closed-loop control system over an open-loop control system?
Click to flip
Closed-loop systems can correct errors and maintain desired output despite disturbances, whereas open-loop systems cannot.
Click to flip
In which fields are control systems commonly applied?
Click to flip
Control systems are used in various fields, including manufacturing, robotics, aerospace, automotive, and electronics.
Click to flip
What distinguishes a feedback control system from a feedforward control system?
Click to flip
A feedback control system adjusts its input based on the output, while a feedforward system adjusts input based on predicted disturbance changes.
Click to flip
What is 'process control' in the context of control systems?
Click to flip
Process control refers to the use of control systems in industrial production to maintain the operational parameters within desired limits.
Click to flip
What are adaptive control systems?
Click to flip
Adaptive control systems dynamically adjust their parameters in response to changes in environmental or system dynamics.
Click to flip
What is model predictive control (MPC)?
Click to flip
MPC is a type of control algorithm that uses a model to predict future outcomes and optimize control moves.
Click to flip
What is robust control in control systems?
Click to flip
Robust control deals with systems affected by uncertainties, aiming to ensure performance under different conditions.
Click to flip
What distinguishes a decentralized control system?
Click to flip
In a decentralized control system, control is distributed among multiple controllers that work independently with limited information sharing.
Click to flip
What is meant by 'fuzzy control systems'?
Click to flip
Fuzzy control systems utilize fuzzy logic for decision making, allowing for handling uncertainty and imprecision.
Click to flip
Define a real-time control system.
Click to flip
A real-time control system processes data and responds rapidly enough to affect the ongoing process or system behavior.
Click to flip
What is a hybrid control system?
Click to flip
A hybrid control system combines both continuous (analog) and discrete (digital) control processes.
