摘要
A simultaneous rapid open and closed loop bode measurement plot (26, 27) is described in which testing of the servo controlled instrument (9) occurs under closed loop conditions using a binary pseudo-random sequence. The binary pseudo-random sequence (11) is injected into the servo while the system under test is operating closed loop in order to generate bode plots for open loop and closed loop conditions. The present invention provides measurement results approximately 1,000 times faster than a swept sinusoid approach and provides superior dynamic range as compared to random white noise test input sources.
