On Gain Scheduling Trajectory Stabilization for Nonlinear Systems: Theoretical Insights and Experimental Results

International Journal of Robust and Nonlinear Control, Volume 35, Issue 6, Page 2142-2155, April 2025.
ABSTRACT Steering a nonlinear system from an initial state to a desired one is a common task in control. While a nominal trajectory can be obtained rather systematically using a model, for example, via numerical optimization, heuristics, or reinforcement learning, the design of a computationally fast and reliable feedback control law that guarantees ...

Stress analysis of gantry crane cylinder structure

Journal of Physics: Conference Series, 2022
Abstract By building three finite element analysis models for its four-bar metal structure under different amplitudes (the boom span is 13.5m, 22.5m and 34.5m), the relationship between stress, amplitude and load at key parts is established by linear interpolation method; At the same time, the relationship between the measured strain ...
