In this contribution, a method for practical implementation of control systems with compensation of saturation is shown. The technique is applied in linear systems taking as a basis a fault diagnosis mechanism. To this end, the actuators saturation is considered as a fault in the control loop, which is detected and isolated by means of a Fault Diagnosis filters bank, whose residuals are used to make the compensation, providing a control scheme which is robust to this particular case. In order to obtain the filters gains, a H_2/H_inf optimization problem with LMI constraints is used. To verify the properties of the proposed method, a numerical example is presented.
