Loop Shaping by Single-Resonant Controllers for Prescribed Tracking of Sinusoidal References

IEEE transactions on power electronics, 2019
It is well-known that in ac-grid-connected or motor-driving converters, current behavior directly sets the exchange of power between the two. Moreover, in corresponding current plants, most of the disturbance (formed by grid voltage or back EMF and the ...

Robust Stability and Nonlinear Loop-Shaping Design for Hybrid Integrator-Gain-Based Control Systems

American Control Conference, 2019
In this paper, the use of quasi-linear tools for the closed-loop design and analysis of Hybrid Integrator-Gain Systems (HIGS) is considered. A nonlinear motion control design procedure is proposed in which quasi-linear loop-shaping methods, based on ...

Nominal and Robust Loop Shaping

1992 American Control Conference, 1992
In this paper, classical frequency-response multivariable comnpensator design is studied. This problem consists of chosing a linear controller which gives the sensitivity and complementary sensitivity functions desirable properties. The problem is given two formulations as optimal multivariable stability margin (k m ) synthesis (or ?-synthesis ...

Rollercoaster loop shapes

Physics Education, 2005
Many modern rollercoasters feature loops. Although textbook loops are often circular, real rollercoaster loops are not. In this paper, we look into the mathematical description of various possible loop shapes, as well as their riding properties. We also discuss how a study of loop shapes can be used in physics education.

Wilson loop and contour shapes

Physical Review D, 1990
By computing the Wilson loop expectation value {ital W}({ital C}) in the two-dimensional Schwinger model on {ital R}{sup 1}{times}{ital S}{sup 1}, we show that nonleading terms depend on the shape of the contours both on {ital R}{sup 1}{times}{ital R}{sup 1} and {ital R}{sup 1}{times}{ital S}{sup 1}. We also find that the rhombic contour and triangular

A Weighting Function Design Method for the H-infinity Loop-shaping Design Procedure

Chinese Control and Decision Conference, 2018
This paper proposes a shaping weighting function (SWF) design method for the H∞ loop-shaping design procedure of McFarlane and Glover. In the original H∞ loop-shaping design procedure, the amplitude versus frequency (AF) characteristic of the shaped open-

Study of Closed loop Cuk converter controlled by Loop Shaping Method

International Conference on Industrial and Information Systems, 2018
This paper presents the detailed analysis of the Cuk converter in closed loop operation. The average modeling is done and the small signal analysis is carried out for linearising the system.

Tree-shaped networks with loops

International Journal of Heat and Mass Transfer, 2005
Abstract Dendritic flow architectures are being contemplated for thermal designs that provide high heat transfer densities for the cooling of electronics. Optimized tree networks maximize the flow access between one point (source, sink) and an infinity of points (line, area, volume).
