Control Algorithm Design

R2026b

Controller gain computation, PI and PR controllers, phase-locked loops, reference frame transforms, signal conditioning

Use these blocks to implement the signal chain from sensor input to PWM output. Gain computation blocks calculate PI gains directly from converter specifications, so you can skip manual tuning. Voltage and current regulator blocks close the corresponding control loops for DC-DC, PFC, and resonant topologies. For AC reference tracking in renewable energy applications, use the PR Controller block. Phase-locked loops extract phase angle and frequency from an AC source, and Clarke and Park transforms convert between stationary and rotating reference frames. Use IIR Filter and SinCos Embedded Optimized blocks for signal conditioning and embedded-optimized math.
