Iteratively Convex Frequency Data-Driven Synthesis of Structured MIMO Controllers
Luuk Marceau Spin, Thom Samuels, Dragan Kostic +3
Frequency-response-function-based controller design enables synthesis directly from measured data, avoiding the need for accurate parametric plant models. This paper presents a gen…
Revisiting the generalized first-order reset element with shaping filters
Ali Hosseini, Dragan Kostić, 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…
Reliability Assessment and Performance Enhancement of Reset Control Systems
Ali Hosseini, Dragan Kostić, Hassan HosseinNia
This paper develops a frequency-domain reliability assessment framework for reset control systems. The closed-loop higher-order sinusoidal-input describing function formulation is…
Robust Performance Analysis and Nonlinearity Shaping for Closed-loop Reset Control Systems
S. Ali Hosseini, Dragan Kostić, S. Hassan HosseinNia
Reset elements are nonlinear filters that improve control performance beyond linear time-invariant (LTI) limits but introduce higher-order harmonics that complicate design. Althoug…
