Abstract

See full text

The present disclosure belongs to the technical field of space satellite propulsion, and particularly relates to a digital filter based method for measuring thrust response time of a satellite-borne micro-thruster. The method for measuring thrust response time in the present disclosure includes the following steps: S1: zeroing non-zero initial conditions of a torsional pendulum thrust measurement system to obtain an oscillating differential equation for a thrust measurement system after variable substitution; S2: connecting the digital filter in series behind the thrust measurement system after variable substitution to obtain an equivalent-sensitivity high-frequency thrust measurement system; S3: determining a system response of the equivalent-sensitivity high-frequency thrust measurement system; S4: determining and reading thrust response time of the satellite-borne micro-thruster from the system response; and S5: computing thrust to be measured by means of the system response inversely, and further confirming the thrust response time.
