Abstract This article exposes the implementation of the H2 controller, which is rare in the literature because it is a more robust control and not only errors but also disturbances that can affect the dynamics of the control system are considered. The deduction of the equations for the continuous and discrete case is shown, which is little identified in this type of controllers and finally the implementation of said control over the rotation angle of the rotor of a motor is exposed, which is of great utility and importance. in electrical power systems for the generation and service of energy.
