Improving Circular Path Control Using Extended State Observers for an Industrial Overhead Crane
ABSTRACT In industrial overhead cranes, inverters and motors are used to control motor position, velocity, and acceleration. However, higher‐order derivatives depend on load characteristics, leading to inconsistent jerk profiles and deviations in circular path. Payload sway further contributes to path deviation, and although sway suppression techniques

Model‐Based Method for Local Monitoring of Steel Structures
This paper presents a new method for monitoring steel structures for fatigue cracks. By combining measurements from strain gauges (SG) with structural simulations, it is possible to detect the position and length of cracks in critical areas, which is supported by experimental results.
