Abstract:

In this paper, we propose a method of applying a two-degree-of-freedom (2DOF) control with adaptive filter since such control of an electrodynamic shaker that is not permitted to employ the iteration control method. At first, a mathematical model and an uncertainty weighting are introduced, and a feedback controller is designed using μ-synthesis. 2DOF controller is constituted. Next, an adaptive filter is added for the purpose of improving the control performance. Uncertainty of the system is considered, and an adaptive filter based on the H∞ filtering problem is employed. Lastly, we show the performance of the controller by experiment using an actual equipment with nonlinear characteristic.
