servomechanism
含义: An automatic control system that uses error-sensing negative feedback to correct the performance of a mechanism, typically governing position, speed, or acceleration.
Servomechanisms are central to robotics, industrial automation, aerospace, and precision manufacturing. The system continuously compares actual output with the desired output and adjusts accordingly, minimising error over time. Power steering in cars, autopilot systems in aircraft, and robotic arms on assembly lines all rely on servomechanisms. The abbreviated form 'servo' is widely used in everyday engineering discussion.

起源与历史
From Latin servus (servant, slave) combined with mechanism, from Greek mekhane (contrivance). The compound term was coined in the 1930s to describe automatic control systems that 'serve' a desired function.
