G05 CONTROLLING; REGULATING
Description
G05 CONTROLLING; REGULATING Covers devices, systems, and methods for automatic control and regulation of physical processes, including feedback mechanisms, closed-loop systems, and control instruments. Encompasses a broad range of applications such as temperature regulation, speed control, pressure management, and position adjustment across industrial, mechanical, and electronic systems. Includes both analog and digital control technologies, servomechanisms, governors, and automatic regulators used to maintain desired operational parameters. Excludes specific application-focused controls (e.g., engine ignition systems classified elsewhere) and general measurement instruments without feedback control capability.
IPC and CPC are identically structured here. All 4 subcodes exist in both systems.
2 shared codes have differing titles between IPC and CPC.
