| Research Abstract |
This research project developed the following matters:
(1) The new robust stability theorem is presented by using phase information of model errors. It breaks through the conservative performances which are caused by the small gain theorem.
(2) The new measurement of phase information of model error is given, where the model error in both gain and phase can be easily estimated form delay between the step responses of the plant and the model.
(3) The information on the model error is used to improve the stability via error compensation. This yields better performances than H inf control.
(4) The multi-degree of freedom control for single-input and single output is presented such that the reference response, disturbance rejection and robust stability can be adjusted independently.
(5) The multi-degree of freedom control is developed for multi-inputs and multi-outputs by robust decoupling and stability of diagonally dominant matrix.
(6) This method is applied to time-delay systems and yields Control systems with high robust stability for large delay.
(7) The above results are systematized as model bridge control.
