Behavior

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

Connected concepts

Limits and interpretation

  • Connected rising/falling rates limit elapsed sample changes. Ideal continuous-rate dynamics 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.

Implementation sources

This reference follows the public interface and locally verified numerical checks for an upcoming release.
