Identifying spatially-localized instability mechanisms using sparse optimization
Talha Mushtaq, Maziar S. Hemati
Recent investigations have established the physical relevance of spatially-localized instability mechanisms in fluid dynamics and their potential for technological innovations in f…
Structured Input-Output Modeling and Robust Stability Analysis of Compressible Flows
Diganta Bhattacharjee, Talha Mushtaq, Peter Seiler +1
The recently introduced structured input-output analysis is a powerful method for capturing nonlinear phenomena associated with incompressible flows, and this paper extends that me…
On the convexity of static output feedback control synthesis for systems with lossless nonlinearities
Talha Mushtaq, Peter Seiler, Maziar S. Hemati
Computing a stabilizing static output-feedback (SOF) controller is an NP-hard problem, in general. Yet, these controllers have amassed popularity in recent years because of their p…
Exact Solution for the Rank-One Structured Singular Value with Repeated Complex Full-Block Uncertainty
Talha Mushtaq, Peter Seiler, Maziar S. Hemati
In this note, we present an exact solution for the structured singular value (SSV) of rank-one complex matrices with repeated complex full-block uncertainty. A key step in the proo…
Structured Singular Value of a Repeated Complex Full-Block Uncertainty
Talha Mushtaq, Diganta Bhattacharjee, Peter Seiler +1
The structured singular value (SSV), or mu, is used to assess the robust stability and performance of an uncertain linear time-invariant system. Existing algorithms compute upper a…
Estimating Regions of Attraction for Transitional Flows using Quadratic Constraints
Aniketh Kalur, Talha Mushtaq, Peter Seiler +1
This letter describes a method for estimating regions of attraction and bounds on permissible perturbation amplitudes in nonlinear fluids systems. The proposed approach exploits qu…
Reducing transient energy growth in a channel flow using static output feedback control
Huaijin Yao, Yiyang Sun, Talha Mushtaq +1
Transient energy growth of flow perturbations is an important mechanism for laminar-to-turbulent transition that can be mitigated with feedback control. Linear quadratic optimal co…
