👉 Hung engineering, also known as the "hung problem," is a concept in control theory and robotics that describes the challenge of maintaining stable motion when a system's dynamics are not fully known or are subject to disturbances. It arises when a robotic system, such as a robot arm or an autonomous vehicle, attempts to follow a desired trajectory but encounters uncertainties in its model, external forces, or environmental conditions. These uncertainties can cause deviations from the intended path, leading to oscillations or instability. The term "hung" metaphorically refers to the system appearing to be stuck or unstable, much like a bird in flight that struggles to maintain its course due to unforeseen gusts. Engineers address hung engineering through advanced control strategies, such as adaptive control, robust control, and model predictive control, to ensure the system can compensate for these uncertainties and maintain stable, precise motion.
