This paper presents a fault-tolerant (FT) switching control system structure and proposes an FT controller design methodology for systems vulnerable to actuator and sensor faults. The working effectiveness of the i-th actuator/sensor (which is assumed to be known) is represented as a time varying parameter δi(t) where δi(t) ∈ {0, c2, …, cs−1, 1} and where δi(t) = 0 represents a component failure at...
There has been significant interest in the use of HTTP adaptive streaming for live or on-demand video over the Internet in recent years. To mitigate the streaming transmission delay and reduce the networking overhead, an effective and critical approach is to utilize cache servers between the origin servers and the heterogeneous clients. As the underlying protocol for web transactions, HTTP has great...
A Rectangular Interval Power Flow (RIPF) method is proposed to improve solutions for intervals of power flow problems due to nondeterministic characteristics of demand loads and output of generators. It is based on affine arithmetic which is a self-validated numerical analysis and serves to improve the interval results through optimization method. Since no approximation is presumed, the RIPF method...
