Implementing Fixed-Point Programming for DSP PR Controllers

Today, we continue our work on fixed-point programming, which is quite significant for using PR control, especially since floating-point microcontrollers are expensive. Previously, in floating-point development, we discussed the discretization and code implementation of the Proportional Resonant Controller (QPR). For fixed-point implementation: Considering quantization errors, we directly run the IIR2 function of the PR controller … Read more
