Safety Interlocks for Control Systems

Overview

Safety interlocks are protective mechanisms that prevent equipment damage and ensure safe operation. In control systems, the primary risks are output saturation and exceeding safe operating limits.

Implementation Pattern

Always check safety conditions BEFORE applying control outputs:

def apply_safety_limits(measurement, command, max_limit, min_limit, max_output, min_output):
    """
    Apply safety checks and return safe command.
