We report an adaptive feedforward controller to address the ill-conditioned dynamic hysteresis on a custom-developed magnetostrictive vibration shaker. The vibration shaker works within low-frequency bandwidth. Magnetostrictive-induced hysteresis is a main issue that affects excitation waveform repl...
