Development and optimization of stepping algorithm and motion control for piezoelectric walking drives
General Introduction on nuclear fusion (reading is strongly advised!) Piezoelectric walking drives are used in the DTT ECRH launcher to drive the steering mirror. These systems include a set of piezoelectric stack actuators that produce a walking motion on a slider, thus moving it longitudinally. The actuators are currently controlled by a proprietary board. However,
