Open-loop controller
From Free net encyclopedia
(Redirected from Open loop control)
An open-loop controller is a type of reactive controller which computes its input into the system using only the current state and its model of the system. It does not use feedback to determine if its input has achieved the desired goal.
This means that a true open-loop system can not engage in machine learning and can also not correct its error.
Open-loop control is useful for well defined systems where a the relationship between input and the resultant state can be modeled by a mathematical formula. For example determining the voltage to be fed to a motor in order to achieve a desired velocity would be a good application of open-loop control.
