Detailed Description

The Summer component sums two or more inputs. These can be pilot control inputs or state variables, and a bias can also be added in using the BIAS keyword. The form of the summer component specification is:

    <summer name="{string}">
      <input> {string} </input>
      <input> {string} </input>
      <bias> {number} </bias>
      <clipto>
         <min> {number} </min>
         <max> {number} </max>
      </clipto>
      <output> {string} </output>
    </summer>

Note that in the case of an input property the property name may be immediately preceded by a minus sign. Here's an example of a summer component specification:

    <summer name="Roll A/P Error summer">
      <input> velocities/p-rad_sec </input>
      <input> -fcs/roll-ap-wing-leveler </input>
      <input> fcs/roll-ap-error-integrator </input>
      <clipto>
         <min> -1 </min>
         <max>  1 </max> 
      </clipto>
    </summer>

    Notes:

    There can be only one BIAS statement per component.

    There may be any number of inputs.
