What defines a linear control system?

A linear control system follows the principle of superposition, meaning its output is directly proportional to its input.

What is a non-linear control system?

A non-linear control system does not follow the principle of superposition, and small changes in input can cause large changes in output.

What is a digital control system?

A digital control system uses digital signals, typically managed by a microcontroller or computer, to control its components.

What is an analog control system?

An analog control system uses continuous signals to control its components, typically involving analog electronics.

What is the advantage of using a closed-loop control system over an open-loop control system?

Closed-loop systems can correct errors and maintain desired output despite disturbances, whereas open-loop systems cannot.

In which fields are control systems commonly applied?

Control systems are used in various fields, including manufacturing, robotics, aerospace, automotive, and electronics.

What distinguishes a feedback control system from a feedforward control system?

A feedback control system adjusts its input based on the output, while a feedforward system adjusts input based on predicted disturbance changes.

What is 'process control' in the context of control systems?

Process control refers to the use of control systems in industrial production to maintain the operational parameters within desired limits.

What are adaptive control systems?

Adaptive control systems dynamically adjust their parameters in response to changes in environmental or system dynamics.

What is model predictive control (MPC)?

MPC is a type of control algorithm that uses a model to predict future outcomes and optimize control moves.

What is robust control in control systems?

Robust control deals with systems affected by uncertainties, aiming to ensure performance under different conditions.

What distinguishes a decentralized control system?

In a decentralized control system, control is distributed among multiple controllers that work independently with limited information sharing.

What is meant by 'fuzzy control systems'?

Fuzzy control systems utilize fuzzy logic for decision making, allowing for handling uncertainty and imprecision.

Define a real-time control system.

A real-time control system processes data and responds rapidly enough to affect the ongoing process or system behavior.

What is a hybrid control system?

A hybrid control system combines both continuous (analog) and discrete (digital) control processes.
