4.1.4 THE BODE ANALYZER
The Bode Plot Analyzer allows the user the ability to observe the gyro performance under different control
loop gain settings. The servo response or control loop bandwidth can be optimized by adjusting the
proportional and integral gain settings.
Figure 21 Open Loop Response, Bode Analyzer
Figure 18 trace shows a typical open-loop response of the control system. By adjusting the Proportional
gains, Integral gains, and compensator cut-in frequencies the servo system can be designed to provide the
largest bandwidth with the highest control authority while preserving the overall loop stability. Note:
changing the pen color in between different gain settings allows the user to compare the results.
