1. robust control system that is used for controlled plant being placed the desired operation state in response to the position of multiposition actuator, described system comprises:

  • First switch contact, it is coupled to described multiposition actuator, and is configured to provide the first ternary input value as the function of described multiposition actuator status;

    The second switch contact, it is coupled to described multiposition actuator, and is configured to provide the second ternary input value as the function of described multiposition actuator position;

    AndControl logic, it is configured to receive the first and second ternary input values, and come from a plurality of modes of operation of described controlled plant, to determine described desired operation state based on the first and second ternary input values that receive, in wherein said a plurality of mode of operation each all represented by unique combination of the first and second ternary input values of selecting so that from described a plurality of modes of operation one in described a plurality of modes of operation another any conversion all cause by the two the conversion of the first and second ternary input values.
