Control systems are essential in engineering and technology, helping to manage and regulate the behavior of various devices and processes. They use feedback to ensure that a system operates as desired, adjusting inputs based on the output. For example, a thermostat in a home heating system monitors the temperature and turns the heater on or off to maintain a comfortable environment. There are two main types of control systems: open-loop and closed-loop. Open-loop systems operate without feedback, meaning they do not adjust based on the output. In contrast, closed-loop systems continuously monitor the output and make necessary adjustments, providing greater accuracy and stability in controlling processes.
