Active Control Systems are technologies designed to automatically adjust and manage the behavior of a system in real-time. They use sensors to monitor conditions and actuators to implement changes, ensuring optimal performance. Common applications include automotive systems, aerospace engineering, and industrial automation. These systems can enhance stability, improve efficiency, and reduce energy consumption. By continuously analyzing data, active control systems can respond to disturbances or changes in the environment, making them essential in modern engineering and technology. Examples include adaptive cruise control in vehicles and active suspension systems in cars.
