Linear control is like when your parents tell you what you can and can't do. They set rules and boundaries to make sure you are safe and happy.
In the same way, machines and devices need rules to follow to work correctly. Linear control is a set of rules or instructions that a device follows to perform a task.
For example, think of a robot arm that moves up and down. It needs to know how far up and down it can go and how fast it can move. This set of rules is called linear control.
In order to create this set of rules, scientists and engineers use something called math. They create equations that describe how the robot arm should move.
These equations are like a recipe for the machine to follow. If the recipe is correct, the machine will perform its task correctly every time.
Linear control is important because it helps machines work efficiently and safely. It also helps make our everyday lives easier by automating tasks.
