System Identification

System Identification is the process of developing mathematical models of a system based on observed data. By analyzing inputs (what you send to the system) and outputs (how the system responds), engineers can understand and predict the system's behavior. This process helps in designing controllers, diagnosing issues, or optimizing performance without fully knowing the internal workings. Essentially, it’s like learning the rules of a game by watching how it reacts to different moves, enabling accurate predictions and better management of complex systems.
