Deadbeat controller

A deadbeat controller is a type of controller used in engineering to try and make a system do something in the most efficient way possible. It uses mathematical equations to figure out the best way to achieve a certain goal. For example, if you wanted a robot arm to pick up an object, a deadbeat controller could figure out the best way for the arm to move so that it can complete the task as quickly and accurately as possible.
