Control Systems

Control Systems is a core discipline in engineering and computer science that focuses on designing and analyzing systems that manage, command, and regulate the behavior of other devices or systems to achieve a desired result. The fundamental concept relies on feedback loops, where sensors measure a system's output, a controller (often a computer running a specific algorithm) compares this output to a desired setpoint, and an actuator makes adjustments to minimize any detected error. This principle is essential for ensuring stability, performance, and automation in a vast range of applications, from simple household thermostats and automotive cruise control to complex industrial processes and robotic automation.
