| Abstract: | The on-line estimation methods for the time-varying control effectiveness of linear control system are investigated.Sufficient conditions for the matrix to be estimable are given in different cases.The corresponding on-line estimation algorithms based on the observer,equation-resolving and Least-Square(LS) methods are proposed,which are proven to be convergent.The simulation results also illustrate the effectiveness and the robustness of the algorithms. |
