Sažetak
Ultra-high precision positioning is a critical feature of the micro- and nanotechnologies. Precision positioning devices are, however, generally characterized by friction, which negatively impacts their performances. The experimental set-up previously used to characterise these drawbacks is employed again in this work, but the rotary DC motor is substituted by a frictionless linear voice-coil actuator, allowing to simplify the kinematic chain. The force vs. displacement characteristics are hence measured for the actuator itself and when it is coupled to the linear guideways. It is thus experimentally proven that the frictional disturbances of the guideways become predominant. By applying a simple control typology, the performances of the mechatronics system are finally assessed proving that its positioning accuracy and precision, compared to those of the original system, clearly improve.
