Description
Classify an actuator input against a supplied deadzone interval.
Control boundaries and stability terms depend on state history, sign conventions and the full system dynamics. A finite scalar factor, one pole or one frequency sample is not sufficient to establish safe closed-loop behavior.
Classify an actuator input against a supplied deadzone interval.
When to use this tool
Use Actuator Dead Zone Edge Token when checking a supplied saturation, hysteresis or local stability condition.
How to use the tool and how it works
- Enter input, lower, upper, includeEdges. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read inDeadZone, side. Inspect inDeadZone before interpreting the associated values.
Classify an actuator input against a supplied deadzone interval. Require upper >= lower; includeEdges controls endpoint membership; outside returns lower when input <= lower, otherwise upper.1

}Limitations and assumptions
- For a degenerate open interval, the sole endpoint is labeled lower; no physical deadzone is estimated.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Analyze the complete dynamic system and practical constraints before interpreting a local result as robust or safe operation.
