Abstract: (Elsevier B.V.)

The TianQin space-borne gravitational wave detection project plans to deploy three satellites in geocentric orbit, utilizing laser interferometry to measure the relative displacement changes of the test masses (TMs) induced by gravitational waves. Thus, before the scientific detection mode, the TM needs to be precisely injected into the geodesic trajectory via the grabbing positioning and release mechanism (GPRM) with transferred momentum of less than

1 \times 10^{- 5} kgm / s

. In this study, an inchworm-type piezoelectric linear actuator is designed for the GPRM and the deviations from linear motion trajectories are analyzed. By developing a dynamic model with experimental data, the motion asymmetry of the driving mechanism within the actuator is identified as the primary cause of nonlinear trajectories. Consequently, a control methodology of the reciprocating single step motion is introduced that effectively suppresses the deflections by approximately 10 times and its potential applications for GPRM operations in orbit is discussed.
