Equation 3c is the transfer function of the ideal differentiator circuit of Figure 1. To convert this to a Bode plot, we must replace the complex variable s with its imaginary part to find the change of the circuit's gain as frequency changes, the magnitude and phase shift of the transfer function can be found.

Equation 7. The phase of the transfer function in Equation 3 at a given frequency can be calculated as. Equation 8. As can be seen, the phase of C(j ) has two parts: a constant phase of - /2 due to the pole at the origin, and a variable part as a function of frequency . ... Plot the loop Bode plot and verify the phase margin. Check the gain ...

Higher crossovers can be achieved using a lead compensator with proportional gain. Bode plots of the suggested controller and the resulting transfer function are shown in Figure 4.4. The controller shown provides an additional 42( phase margin for a closed loop system crossover at 40 rad/s with 55( total phase …
