     - `beta`, `Ni` and `TOL` are used when finding `D_nonlinar`. 
     - `method` determines the linearization method: 'jacobian' or 'perturbation'
     - `is_programmed_ref`: if set to true, the reference will be considered programmed, meaning that the controller is aware of the future values of the reference signal.
-    -`noise_power` power of white noise on the output
-    -`dist_amp` the amplitude of disturbance on the output. The disturbance is considered to be a pulse signal.
-    -`dist_time` the time when the disturbance is applied
