What is plant in closed-loop control?

A plant in control theory is the combination of process and actuator. A plant is often referred to with a transfer function (commonly in the s-domain) which indicates the relation between an input signal and the output signal of a system without feedback, commonly determined by physical properties of the system.

What does plant mean in control?

The object whose output you try to control is called the plant. The output of the plant is measured by the component called the sensor and the measured output is then compared to the desired output. The difference between the desired and measured output is the error.

Why is it called a closed-loop system?

Ideal closed-loop systems produce no waste. They are called "closed" because products have a circular life cycle, beginning as raw materials and either being recycled into replacement products, returning to the original raw materials, or being returned to the environment as biodegradable waste.

What is a plant equation?

Photosynthesis Equation

This equation may be simplified as: 6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂.
