摘要：A multiexciter digitally swept-sinewave vibration test controller employing an adaptive control method which compensates for nonlinear and time variant physical characteristics of a system under test and for instrumentation errors. A system under test (12) is stimulated using an exciter array (26) and respon is measured using a nsor array (28). The exciter array (26) is driven by signals produced by a digital vector swept oscillator (18). A control loop (14) is ud to modify signals to the exciter array (26) bad upon input from the nsor array (28). A digital processing system (24) process signals in the control loop (14). Within the digital processing system (24), a system impedance matrix (44) containing values reprenting the inver of respon characteristics of the system under test (12) is updated to approximate an ''actual'' system impedance matrix.
cution
A drive signal matrix (52) is modified to cau the digital vector swept oscillator (18) to produce updated drive signals. An amount by which the updated system impedance matrix (44) is allowed to modify each iteration of the drive signal matrix (52) is controlled by a variable adjustment gain scalar (48). Value of the adjustment gain scalar (48) is determined using values obtained in a preceding iteration of the control cycle.infiniti
