Abstract

Aimed at the problem that the vibration isolation system is subject to strong interference or impact, which causes the controller output signal to exceed the operating current range of the actuator, which makes the control system fail. An adaptive saturation suppression algorithm is proposed. First, the characteristics of the electromagnetic actuator are analyzed, and it is concluded that the actuator will generate magnetic saturation with the increase of current and enter the saturation zone. Then, on the basis of the FXLMS algorithm, a suppression factor is introduced to modify the update of the control weight coefficient, thereby enhancing the robustness of the system under strong interference or impact. The simulation and test results show that the algorithm solves the saturation effect of the actuator well, achieves a significant control effect on dual-frequency excitation, and exhibits good robustness when subjected to impact.
