Overview

Easy and accurate calculation

Calculate the z-domain coefficients of digital compensators so they can be implemented by digital devices, e.g., FPGAs or DSPs. Digital regulators are obtained following the discretization of their corresponding analog compensators, which are calculated using the analog approach of SmartCtrl.

Digital Control Factors

Three factors are taken into account on digital control calculations:

  • Sampling frequency of the regulator.
  • Number of bits to represent the resolution in fixed point the coefficients of the obtained compensators. Overall time delay in the control loop.

It is a good practice to compare the discretized compensator with the original analog one.

The new Equations Editor

  • This built-in function supports the definition of customized plants and sensors transfer functions.
  • Multiple transfer functions can be plotted at the same time to compare the results.
  • Sensitivity analysis can be performed for any of the parameter of custom model.

Buck Converter Example

In the buck converter example below, the analog controller is designed first. Then the controller is redesigned with the digital control delay taken into account. The difference with and without the digital control delay can be clearly seen in the phase Bode plot of the loop transfer function. The analog controller is then discretized for digital implementation.
