New method simplifies modeling of convex objects for electromagnetic scattering analysis.

Process Optimization

Disturbance observer (DOB) design using frequency response data was studied. The goal was to improve disturbance estimation and compensation in industrial applications. The researchers transformed complex constraints into simpler forms to maximize the bandwidth of DOB through convex optimization. Simulation results confirmed the effectiveness of this approach.
