The SVC (Static Var Compensator) based on voltage source converter (VSC) is used for voltage regulation in transmission and distribution system. The SVC can rapidly supply dynamic VARs required during system faults for voltage support. The apparent impedance is influenced by the reactive power injected or absorbed by the SVC, which will result in the under reaching or over reaching of distance ...

Smart microgrids offer a new challenging domain for power theories and compensation techniques, because they include a variety of intermittent power sources, which can have dynamic impact on power flow, voltage regulation, and distribution losses. When operating in the islanded mode, low-voltage smart microgrids can also exhibit considerable variation of amplitude and frequency of the voltage s...

This paper presents a uniied systematic framework of dynamic controller synthesis for systems described by Takagi-Sugeno (T-S) model. The control laws are in the form of so-called parallel distributed compensation (PDC) introduced by the authors. This paper provides two results. First, we introduce the notion of dynamic PDC compensators and provide a set of suf-cient LMI conditions for the exis...

We describe the use of appropriate type simple resistor and capacitor (RC) compensators, which properly connected to a power amplifier, can improve the dynamic performance of MEMS (Microelectromechanical Systems) nanopositioners. Research on compensators led to the design of several simple RC compensators that may be appropriate for the NIST symmetric dual parallel lever nanopositioner. Using b...

The compensating devices are controlled in the structure of automatic control system conjunction with sensors included a particular node power grid. But overall state local grid for reactive flow is not considered. It proposed to generate signals correction by processing information obtained monitoring from remote voltage and current distribution possible use matrix method forming adjust parame...

Feedback control of fluids is often achieved with limited state measurements. Effective approaches utilize compensators, which can be computed using linear quadratic Gaussian (LQG) or MinMax control designs. However, to achieve real-time control algorithms, these compensators must have low computational complexity. Model reduction methods are a natural choice to build reduced-order compensators...

PUP Compensator In this paper, we consider linear time-invariant multi-input multi-output (MIMO) systems that are stabilizable by proportionalintegral (PI) compensators. Such systems are also stabilizable by a PI-type compensator to be denoted by PIP. The P I P compensator consists of a PI compensator in the feedforward loop preceding the plant to be controlled, and a proportional gain in a fee...

In this paper symbolic quantifier elimination methods are used to explore the fragility of feedback compensators, and to design feedback systems with non-fragile compensators. A compensator is said to be fragile if given variations in compensator parameters result in significant deterioration of feedback performance. The issue of fragility is important in understanding the level of acurracy req...
