Performance-based Adaptation Termination for Preventing Parameter Drift in Adaptive Vibration Suppression
Juan Augusto Paredes Salazar, Ankit Goel
Parameter drift remains a practical limitation of adaptive vibration control systems, particularly when persistence of excitation diminishes after disturbance attenuation or when m…
Model-free Adaptive Output Feedback Vibration Suppression in a Cantilever Beam
Juan Augusto Paredes Salazar, Ankit Goel
This paper presents a model-free adaptive control approach to suppress vibrations in a cantilevered beam excited by an unknown disturbance. The cantilevered beam under harmonic exc…
Low-Order Controller Design for Aeroelastic Vibration Suppression
Mohammad Mirtaba, Juan Augusto Paredes Salazar, Daning Huang +1
This paper presents an minimization-based output-feedback controller for active aeroelastic vibration suppression in a cantilevered beam. First…
Data-driven Pressure Recovery in Diffusers
Juan Augusto Paredes Salazar, Ankit Goel, Rowen Costich +3
This paper investigates the application of a data-driven technique based on retrospective cost optimization to optimize the frequency of mass injection into an S-shaped diffuser, w…
Computing Safe Control Inputs using Discrete-Time Matrix Control Barrier Functions via Convex Optimization
James Usevitch, Juan Augusto Paredes Salazar, Ankit Goel
Control barrier functions (CBFs) have seen widespread success in providing forward invariance and safety guarantees for dynamical control systems. A crucial limitation of discrete-…
Predictive Control Barrier Functions for Discrete-Time Linear Systems with Unmodeled Delays
Juan Augusto Paredes Salazar, James Usevitch, Ankit Goel
This paper introduces a predictive control barrier function (PCBF) framework for enforcing state constraints in discrete-time systems with unknown relative degree, which can be cau…
