The integral quadratic constraints (IQC) approach facilitates a systematic and efficient
analysis of robust stability and performance for uncertain dynamical systems based on linear …

We present a new approach to mixed H_2/H_∞ output feedback control synthesis. Our
method uses nonsmooth mathematical programming techniques to compute locally optimal …

We revisit robust complex‐and mixed‐µ‐synthesis problems based on upper bounds and
show that they can be recast as specially structured controller design programs. The …

We present a nonsmooth optimization technique for nonconvex maximum eigenvalue
functions and for nonsmooth functions which are infinite maxima of eigenvalue functions. We …

Feedback controllers with specific structure arise frequently in applications because they are
easily apprehended by design engineers and facilitate on‐board implementations and re …

We present a new proximity control bundle algorithm to minimize nonsmooth and
nonconvex locally Lipschitz functions. In contrast with the traditional oracle-based methods …

Many questions of robust control analysis and synthesis fundamentally involve nonsmooth
sets and functions, and their variational properties. Central examples include distances to …

The DC-DC converter severs as one of the crucial components in DC microgrid applications.
In this paper, a novel low frequency current-mode control strategy is proposed to improve …

We propose a bundle trust-region algorithm to minimize locally Lipschitz functions which are
potentially nonsmooth and nonconvex. We prove global convergence of our method and …

In this paper, an H∞ negative imaginary static output feedback (SOF) controller is designed
for a low frequency (LF) networked control system (NCS) with time-delays. A difference …
