Sparse Control Synthesis for Uncertain Responsive Loads With Stochastic Stability Guarantees

چکیده
Recent studies have demonstrated the potential of flexible loads in providing frequency response services. However, uncertainty and variability various weather-related end-use behavioral factors often affect demand-side control performance. This work addresses this problem with design a to achieve under load uncertainties. Our approach involves modeling uncertainties via stochastic processes that appear as both multiplicative additive system states closed-loop power dynamics. Extending recently developed mean square exponential stability (MSES) results for systems, we formulate multi-objective linear matrix inequality (LMI)-based optimal synthesis problems not only guarantee stability, but also promote sparsity, enhance transient performance, maximize allowable The fundamental trade-off between maximum ( critical ) levels stabilizing efforts is established. Moreover, sparse generalized realistic systems scenario which partial-state measurements are available. Detailed numerical carried out on IEEE 39-bus demonstrate performance controllers enhancing uncertainties; well illustrate efforts.

LTL Control in Uncertain Environments with Probabilistic Satisfaction Guarantees
We present a method to generate a robot control strategy that maximizes the probability to accomplish a task. The task is given as a Linear Temporal Logic (LTL) formula over a set of properties that can be satisfied at the regions of a partitioned environment. We assume that the probabilities with which the properties are satisfied at the regions are known, and the robot can determine the truth...
متن کاملStochastic simulation of riser-sections with uncertain measured pressure loads and/or uncertain material properties
We investigate three-dimensional problems in solid mechanics with stochastic loading or material properties. To solve these problems, we use a spectral expansion of the solution and random inputs based on Askey-type orthogonal polynomials in terms of independent, identically distributed (i.i.d) random variables. A Galerkin procedure using these types of expansions, the generalized Polynomial Ch...
متن کاملDelay-dependent robust stabilization and $H_{infty}$ control for uncertain stochastic T-S fuzzy systems with multiple time delays
In this paper, the problems of robust stabilization and$H_{infty}$ control for uncertain stochastic systems withmultiple time delays represented by the Takagi-Sugeno (T-S) fuzzymodel have been studied. By constructing a new Lyapunov-Krasovskiifunctional (LKF) and using the bounding techniques, sufficientconditions for the delay-dependent robust stabilization and $H_{infty}$ control scheme are p...
متن کاملCleaning uncertain data with quality guarantees
Uncertain or imprecise data are pervasive in applications like location-based services, sensor monitoring, and data collection and integration. For these applications, probabilistic databases can be used to store uncertain data, and querying facilities are provided to yield answers with statistical confidence. Given that a limited amount of resources is available to “clean” the database (e.g., ...
متن کاملNonnegative Sparse PCA with Provable Guarantees
We introduce a novel algorithm to compute nonnegative sparse principal components of positive semidefinite (PSD) matrices. Our algorithm comes with approximation guarantees contingent on the spectral profile of the input matrix A: the sharper the eigenvalue decay, the better the quality of the approximation. If the eigenvalues decay like any asymptotically vanishing function, we can approximate...
