    control means measuring the value of controlled variable of the System & applying the manipluted variableto the system to correct the devation

    Type of Control

    Open Loop Closed Loop

    Open Loop Control System :also called a non-feedback controller, is a type of controller which computes its input into a system using only the current state and its model of the system.
    A characteristic of the open-loop controller is that it does not use feedback to determine if its input has achieved the desired goal. This means that the system does not observe the output of the
    processes that it is controlling



    Closed Loop Control System : The output of the system y(t) is fed back through a sensor measurement F to the reference value r(t). The controller C then takes the error e (difference)between the reference and the output to change the inputs u to the system under control P. This is shown in the figure. This kind of controller is a
    closed-loop controller or feedback controller.
