To conclude, we showed that FdRA might be a helpful analytical method to not only gain insight into the dynamics of various systems but also suggests the appropriate drug dosing regimen. Quote from: Fungus on May 31,pm. With Eqs. Isaksson, C. The FdRA not only provides valuable insight into the dynamic behavior of a system but also enables the identification of the systems mathematical structure solely through observation of its responses to different inputs.

In the Bode Editor , review the gain margin and phase margin for the current compensator design. The design requires a gain margin greater than 20 dB and phase margin greater than 40 degrees. The current design does not meet either of these requirements. To increase the stability margins, add a lead network to the compensator. To specify the location of the lead network pole, click on the magnitude response. The app adds a real pole red X and real zero red O to the compensator and to the Bode Editor plot.
In the Bode Editor , drag the pole and zero to change their locations. To decrease the magnitude of a pole or zero, drag it towards the left. Since the pole and zero are on the negative real axis, dragging them to the left moves them closer to the origin in the complex plane. As you drag a pole or zero, the app displays the new value in the status bar, on the right side. As an initial estimate, drag the zero to a location around -7 and the pole to a location around The phase margin meets the design requirements; however, the gain margin is still too low.
In the Compensator Editor dialog box, in the Dynamics section, click the Lead row. This value is near the slowest left-most pole of the DC motor plant. In the Real Pole text box, specify a value of , and press Enter. When you modify a lead network parameters, the Compensator and response plots update automatically. In the app, in the Bode Editor , the gain margin of To add robustness to the system, in the Compensator Editor dialog box, decrease the compensator gain to The gain margin increases to In Control System Designer , in the response plots, compare the system performance to the design requirements.

Bode Diagram Design Bode diagram design is an interactive graphical method of modifying a compensator to achieve a specific open-loop response loop shaping.
Rise time of less than 0. By changing the value of gain K in the transfer function brings up or brings down the log-magnitude curve by the proportionate amount. The gain factor K has no effect on the phase curve of the bode plot. Here, we implemented the bode plot of gain factor K for the comprehensive understanding of the readers. For differentiator, the bode-plot is obtained as:.
Whereas, the phase plot is a straight line with angle 90 o. Here, we implemented the Bode plot of a differentiator for the comprehensive understanding of the readers. Similarly, for Integrator , the bode-plot is obtained as:.
Whereas, the phase plot is a straight line with angle o. Here, we implemented the bode plot of Integrator for the comprehensive understanding of the readers. For a simple phase-lag network, the bode-plot is obtained as:. Where T is a real constant. For Magnitude Plot. For Phase plot. Which means that phase plot would be a straight line at 0.
Which means that phase plot would be a straight line with Which means that phase plot would be a straight line at o. Here, we implemented the Bode plot of a Simple Phase Lag network for the comprehensive understanding of the readers.
Similarly, for a simple phase-lead network, the bode-plot is obtained as:. For magnitude plot. Which means that phase plot would be a straight line at 90 o. Here, we implemented the bode plot of a Simple Phase Lead network for the comprehensive understanding of the readers. The transfer function for typical quadratic function can be written as. The Magnitude Plot is obtained from. The above equation can be simplified as.
And the Phase Plot is obtained from. The bode-plot shown in the following figure was obtained from Matlab Software. Similarly, for higher frequencies that value of magnitude is approximated by. Similarly, for phase plot. Which means that phase plot would be a straight line at 0 o. Here, we implemented the bode plot of a second-order network for the comprehensive understanding of the readers.
