Classification of Control Systems

Control systems are classified into open-loop and closed-loop (feedback) systems, as well as manual vs. automatic, linear vs. nonlinear, time-invariant vs. time-variant, and SISO vs. MIMO.

Open-loop systems lack feedback, making them less accurate, while closed-loop systems use feedback to improve accuracy and stability. Manual systems rely on human input, and automatic systems are self-operating. Linear systems have predictable, proportional relationships, while nonlinear systems do not. Time-invariant systems maintain constant properties, while time-variant systems change over time. SISO (single input, single output) and MIMO (multiple input, multiple output) systems differ in their input/output structure.
