Description: (1) Position PID control output and the entire state of the past, used the accumulated value of the error incremental PID output only error with the current beat and shot the first two, and therefore the position of the cumulative error PID control relatively greater (2) incremental PID control is to control the amount of incremental output, there is no integral action, so this method is suitable for the implementation of the object body with integral components, such as stepper motors, etc., and positional PID applicable Object actuators without integral components, such as electro-hydraulic servo valve. (3) Since the incremental PID control output increment, if the computer failure, malfunction less affected, while executing agency itself has memory function, can remain in place, will not seriously affect the operation of the system, and positional output directly corresponds to the output object, so a greater impact on the system.
