Abstract
Active vibration controllers are designed to mitigate chatter vibrations and increase the productivity of machines. Such controllers, however, often do not perform well in real applications if uncertainties are present in the system. In this study, a controller design is presented for a test configuration, where the actuation is utilized by an electromagnetic actuator. The robust stability charts, which take into account the bounded uncertainties in the measured frequency response functions (FRFs), are calculated in frequency domain using the zero-order approximation method. The predictions for the experimental configuration are validated in cutting tests.
