The transfer function—gain and phase as a function of frequency—provides valuable information about a control loop’s speed and stability. Knowing a control loop’s transfer function, as well as the ...

Figure 3. Unloaded buck-converter control transfer function. Because a digital controller sees a sampled version of the buck converter, the model has to be transformed into a discrete-time version.

These models are then solved, to find the important transfer functions of the converter and its regulator system. Finally, the feedback loop is modeled, analyzed, ... Ch 9: Controller Design. 8%. Week ...

To be effective, however, the adaptive-control system must employ an IC that uses minimal external components and still provides all the necessary functions. An adaptive control IC can be used in ...

Analytical approach demonstrates how the open-loop gain and phase prediction can determine the optimal compensation network for a zero current switched (ZCS) dc-dc, variable frequency ...
