This paper proposes a feedback-optimization-based control method for linear time-invariant systems,which is aimed to exponentially stabilize the system and,meanwhile,drive the system output to an approximate solution of an optimization problem with convex set constraints and affine inequality *** ensure the exponential stability of the closed-loop system,the original optimization problem is first reformulated into a counterpart that has only convex set *** is shown that the optimal solution of the new optimization problem is an approximate optimal solution of the original ***,based on this new optimization problem,the projected primal–dual gradient dynamics algorithm is used to design the *** using the singular perturbation method,sufficient conditions are provided to ensure the exponential stability of the closed-loop *** proposed method is also applied to microgrid control.

Performance models provide insightful perspectives to predict performance and to propose optimization *** there has been much researches,pinpointing bottlenecks of various memory access patterns and reaching high accurate prediction of both regular and irregular programs on various hardware configurations are still not *** work proposes a novel model called process-RAM-feedback(PRF)to quantify the overhead of computation and data transmission time on general-purpose multi-core *** PRF model predicts the cost of instruction for singlecore by a directed acyclic graph(DAG)and the transmission time of memory access between each memory hierarchy through a newly designed cache *** using performance modeling and feedback optimization method,this paper uses PRF model to analyze and optimize convolution,sparse matrix-vector multiplication and sn-sweep as case study for covering with typical regular kernel to irregular and data *** the PRF model,it obtains optimization guidance with various sparsity structures,algorithm designs,and instruction sets support on different data sizes.

关键词： performance model feedback optimization convolution sparse matrix-vector multiplication sn-sweep
