Revisiting the generalized first-order reset element with shaping filters
Ali Hosseini, Dragan KostiÄ, Hassan HosseinNia
Reset control provides a nonlinear approach for improving closed-loop performance beyond the limitations of linear time-invariant controllers. However, the reset action inevitably…
Decentralized Motion and Resonant Damping Control for High-Bandwidth and Cross-Coupling Reduction in MIMO Nanopositioners
Aditya Natu, Hassan HosseinNia
Piezoelectric nanopositioning systems are widely used in precision applications that require nanometer accuracy and high-speed motion; however, lightly damped resonances and pronou…
Digitally Controlled Mechatronic Metamaterials for Actively Induced Targeted Bandgaps
Vivek Gupta, Aditya Natu, S. Hassan HosseinNia
This paper presents an experimental framework for inducing and tuning vibration bandgaps in digitally controlled mechatronic metamaterials. A slender-beam structure instrumented wi…
Robust reset control design for piezo-actuated nano-positioner in presence of hysteresis nonlinearity
Ashkan Sebghati, S. Hassan HosseinNia
In this paper, a robust nonlinear control scheme is designed for the motion control of a class of piezo-actuated nano-positioning systems using frequency-domain analysis. The hyste…
Higher-Order Harmonics Reduction in Reset-Based Control Systems: Application to Precision Positioning Systems
S. Ali Hosseini, Nima Karbasizadeh, S. Hassan HosseiniNia
To address the limitations imposed by Bode's gain-phase relationship in linear controllers, a reset-based filter called the Constant in gain- Lead in phase (CgLp) filter has been i…
Frequency Domain Design of a Reset-Based Filter: An Add-On Nonlinear Filter for Industrial Motion Control
S. Ali Hosseini, Fabian R. Quinten, Luke F. van Eijk +2
This study introduces a modified version of the Constant-in-Gain, Lead-in-Phase (CgLp) filter, which incorporates a feedthrough term in the First-Order Reset Element (FORE) to redu…
