    Study Notes

    • A control system consists of components assembled to achieve a desired output with specified performance based on a given input.
    • Feedback control aims to reduce the difference between the system output and a reference input, particularly in the presence of unpredictable disturbances.
    • The performance of a control system is assessed based on metrics like Transient response and Steady State error.
    • Control systems can be classified into Open Loop Control Systems (e.g., washing machine) and Closed Loop Control Systems (e.g., refrigerator).
    • Closed Loop Control Systems offer greater accuracy and noise sensitivity compared to Open Loop Control Systems.
    • Linear Control Systems have outputs that vary linearly with the input, while time-invariant control systems do not depend on time for their characteristics.
    • Discrete Data Systems involve variables known only at discrete time intervals, while Continuous Data Systems have variables that are a function of continuous time.
    • Control systems can be deterministic if the response to input is predictable and repeatable, or stochastic if it is not.
