Real-Time Implementation of Robust Loop-Shaping Controller for a VSC HVDC System
Energies, 2021 Voltage source converter (VSC) based HVDC systems are one of the most promising technologies for high voltage bulk power transmission. The reliability and stability of a VSC-based HVDC system greatly depends on the design of a proper controller for the ...

IEEE Open Journal of the Solid-State Circuits Society, 2022 This article presents a hybrid 4th-order delta–sigma modulator (DSM). It combines a continuous-time (CT) loop filter and a discrete-time (DT) passive 2nd-order noise-shaping SAR (NS-SAR). Since the 2nd-order NS-SAR is robust against PVT variation,

loop-shaping control of azimuthal combustion instabilities in annular combustors
Journal of Low Frequency Noise, Vibration and Active Control, 2021 Lean combustion technique and annular geometries are preferred in aero-engines and gas turbines, which however may lead to azimuthal combustion instabilities. Active control can be used to stabilize combustion instabilities.

Trajectory-Free Control of Lower-Limb Exoskeletons Through Underactuated Total Energy Shaping
IEEE Access, 2021 Kinematic control approaches for exoskeletons replicate normative joint kinematics associated with one specific task and user at a time, which makes it difficult to adjust to continuously-varying activities during gait training.
