| Abstract: | The application of pseudo-inverse method based flight control reconfiguration in the 6 degrees of freedom aircraft model was introduced. The failure considered here is the control surface effectiveness loss or lock-in-place. Via the appropriate linearization of the control coefficients, the reconfiguration problem was simplified to a problem of solving a linear equations. The real-time digital simulation results were given to indicate the validity of the algorithm. |
