Closed-Loop Signal Shaping With Inner-Loop Model Matching
Volume 4B: Dynamics, Vibration, and Control, 2017Input shaper is a pre-filter, designed to suppress residual vibration of flexible systems. The input shaper can be placed inside the feedback loop, in front of the flexible plant, to avoid exciting the plant vibratory modes. The performance of this so-called closed-loop signal shaping is limited due to the time delay brought about by the input shaper ...

Smooth weight optimization in loop-shaping design
Systems & Control Letters, 2010Smooth variation in the magnitude response of weights facilitates ℋ∞ loop-shaping design, as it prevents the cancellation of important modes of the system, for example, lightly damped poles/zeros of flexible structures, when the shaped plant is formed based on closed-loop design specifications.

9.5 A 13.5b-ENOB Second-Order Noise-Shaping SAR with PVT-Robust Closed-Loop Dynamic Amplifier
IEEE International Solid-State Circuits Conference, 2020Noise shaping (NS) SAR ADCs combine the merits of SAR and Δσ ADCs, and can simultaneously achieve high power efficiency and high resolution. The key operation in an NS SAR is the residue integration.

THE HYSTERESIS LOOP 2. AN ANALYSIS OF THE LOOP SHAPE
Fatigue & Fracture of Engineering Materials & Structures, 1982Abstract— Hysteresis loops of a low carbon steel measured at various temperatures and plastic strain amplitudes are analysed using the statistical theory of the hysteresis loop. It is shown that the parameters of the statistical theory characterizing the saturated hysteresis loop, i.e.

Shape loop space of pro-discrete spaces
2022Loop spaces endowed with a (natural) compact-open topology are important invariants in (algebraic) topology. In the paper [Topology Appl. 261, 29--38 (2019; Zbl 1430.55008)], the author and \textit{B. Mashayekhy} introduced the \(k\)-th shape loop space \(\Omega_{k}^{p}(X,x)\) for the fixed polyhedral expansion \(p:(X,x)\to((X_\lambda,x_\lambda),[p_ ...

1997
The H∞ loop-shaping design procedure (referred to hereafter as LSDP) was used to design fixed gain controllers for the HIRM. It was found that a single fixed gain controller designed for the linearisation ini3005, performed adequately over the whole flight envelope of the HIRM.

Multivariable Loop-Shaping in Bilateral Telemanipulation
Journal of Dynamic Systems, Measurement, and Control, 2005This paper presents an architecture and control methodology for obtaining transparency and stability robustness in a multivariable bilateral teleoperator system. The work presented here extends a previously published single-input, single-output approach to accommodate multivariable systems. The extension entails the use of impedance control techniques,

ON DEGENERATE DOUBLE-LOOP L-SHAPES
Journal of Interconnection Networks, 2006Most of the results about the L-shapes of double-loop networks are given in terms of the four parameters ℓ, h, p, n. But these parameters are not well defined in the degenerate case. Recently, Cheng and Hwang proposed an efficient algorithm to compute the four parameters ℓ, h, p, n of an L-shape which works for both the regular and the degenerate ...

Virtual disturbance loop-shaping for multi-loop PID control
2009 International Conference on Networking, Sensing and Control, 2009In this paper, a new tuning method of the multi-loop PID controller for loop shaping is proposed. The loop shaping problem of maximizing the integral gain of the PID controller under the maximum sensitivity constraint is reduced to a linear programming problem.

Auto-tuning quadcopter using Loop Shaping
2013 International Conference on Computer, Control, Informatics and Its Applications (IC3INA), 2013A novel PD Loop-Shaping strategy to achieve stable and robust Quadrotor control system is proposed in this paper. In order to be able to follow of the scenerio, the developed nonlinear model has to be linearized. By choosing the proper forward loop using loop shaping strategy, a PD auto-tuner is designed.
