| Outline of Final Research Achievements |
We develop a design method of discrete-time Gain-Scheduled (GS) controllers using inexactly provided scheduling parameters for discrete-time Linear Parameter-Varying (LPV) systems, and extend the method to the case in which multiple uncertainty blocks exist for applicability improvement.
We designed GS controllers, which realize disturbance suppression and model-matching for a certain model, for the lateral-directional motions of an experimental aircraft by using our method and a conventional method, and compared their performances with a posteriori analysis and flight tests. It was confirmed in the a posteriori analysis as well as flight tests that the GS controller designed with the conventional method does not guarantee the control performance assured in its design due to the inaccuracy of the scheduling parameter; however, the GS controller designed with our method guarantees the control performance assured in its design. These properties illustrate the usefulness of our method.
