Behavior

y[k] = y[k−1] + clamp(u[k]−y[k−1], −fall_rate Δt, rise_rate Δt). The worked example connects this operation to signals in Lemonergy Studio.

Limits and interpretation

  • Actual elapsed sample duration limits each output change. Ideal continuous slew tracking and continuous zero-crossing localization are not implemented.
  • Shapes and element types are explicit. Values must be finite; automatic reshaping and unit conversion are not performed.

Reference basis

This software operation and its numerical conventions are defined by the public contract and worked example; no external research result is claimed.
