Desired frequency response and resultant overall system response can be seen in Figure 33.
Figure 33. Overall System Bode Plot
Using these values and the equations above the resistors and capacitors around the compensation network can
be calculated.
1. Set RZ1 = 10 k.
2. Calculate RSET using Equation 49; RSET = 8750 . Two resistors in parallel, RSET1 and RSET2, are used to
make up RSET. RSET1 = 9.53 k, RSET2 = 105 k.
5. The required gain of 17.6 dB (7.586) and Equation 52 sets the value for RPZ1. Note actual gain used for this
calculation was 20 dB (10), this ensures that the gain of the transfer function is high enough, RPZ1 = 6.2 k.
Using MathCAD the above values were used to draw the actual Bode plot for gain and phase. From these plots
the crossover frequency, phase margin and gain margin can be recorded.
