Control systems are automated systems that use various methods to maintain a desired output or behaviour. These systems are widely used in various industries such as manufacturing, aerospace, and telecommunications to regulate and automate processes. They consist of sensors, actuators, controllers, and algorithms that work together to manage the system's inputs, outputs, and internal operations. Control systems can be classified into two types: open-loop and closed-loop. Open-loop systems operate on fixed inputs, while closed-loop systems use feedback to adjust their outputs. Control systems play a crucial role in optimising performance, increasing efficiency, and improving safety in various fields.
