Fixed-Point Slew-Rate Limiter Algorithm for Embedded Trajectory Protection

Jamie Davis authored a C++ implementation of a real-time slew-rate limiter with variable rise and fall constraints. The algorithm is designed for bare-metal embedded systems to protect actuators from destructive transients. The code was uploaded to figshare on 2026-05-31 under a CC-BY-4.0 license.

Use Cases

• Implementing trajectory smoothing for actuator control based on the described independent rise and fall rate constraints.
• Protecting downstream hardware from electrical sensor glitches based on the algorithm's real-time, sample-by-sample processing.
• Developing zero-heap embedded software based on the described bounded memory and static parameter architecture.
• Optimizing loop latency in control systems based on the branch-optimized conditional step structure.

Strengths

• The algorithm uses zero bytes of heap memory and bypasses dynamic allocation.
• The code incorporates 32-bit hardware saturation clamping to eliminate integer wrap-around errors.
• The license is Creative Commons Attribution 4.0 International (CC BY 4.0), permitting open use.

Limitations

• The dataset is a 3.9 KB text file, indicating a very limited scope focused solely on algorithm source code.
• Column-level documentation is absent; field semantics must be inferred from the code after download.
• Row count is unknown, which may limit suitability assessment for data-centric applications.
