In the fast tool servo (FTS) system for microstructure surface cutting, dynamic voltage hysteresis of piezoelectric actuators (PEAs) and cutting force produced in manufacturing affect driving accuracy performance. For a multi-input-single-output (MISO) system, this paper, model based on rate-dependent Prandtl–Ishlinskii is proposed. A backpropagation neural network (BPNN) established to describe cross-coupling effect between applied external load. An inverse developed compensate nonlinearity...
During the ultraprecise cutting of micro-structure surface with fast tool servo (FTS), hysteresis piezoelectric actuators (PEAs) are affected by dynamic voltage excitations and real-time force, which declines accuracy performance. In this paper, for a multi-input-single-output (MISO) system, cross-coupling rate-dependent Prandtl-Ishlinskii (CRPI) model is proposed identified PEAs under excitation external loads. A reference adaptive control method then presented to eliminate positioning...
