Parameter Sensitivity Analysis for Design and Control of Force Transmission Systems

Abstract

We apply sensitivity analysis to the design and control of force transmission systems. With this approach, the e ect of the values of the system parameters on the response can beinvestigated: transmission ratio, sensor placement, damping and allowable load variation. It is found that feedback m ust be applied to reduce the sensitivity of the system response to the load. Based on these observations, a loop shaped feedback compensator design is proposed. Such compensators can compensate for the nonlinear behavior of the transmissions due to friction, while exhibiting good disturbance rejection and robustness. This is achieved without detailed knowledge of friction behavior and without measurement nor estimation of velocity. Experimental results using a test bench are discussed.

Transport and retention from single to multiple fractures in crystalline rock at Äspö (Sweden): 1. Evaluation of tracer test results and sensitivity analysis

“…The Laplace transform formulation of the model distinguishes / 0 as a four‐parameter “transfer function.” A useful sensitivity measure applicable in the Laplace domain to any “transfer function,” is the Bode sensitivity function (BSF) [e.g., Hayward and Cruz‐Hernández , 1998]. If G is a transfer function then the BSFs are defined by where α is a vector of the system parameters, in our case , σ τ 2 , ψ and ζ .…”

Rigorous Mathematical Steps for Sensitivity Analysis of High Impedance Ground Fault Detection in Power Distribution Systems

“…When a small change in x produces a large change in function y = f (x), then y is relatively sensitive to changes in x. The derivative f'(x) is a measure of this sensitivity (Weir et al, 2005), (Hayward & Cruz-Hernandez, 1998). The equation dy = f'(x) dx conveys the sensitivity of the output of "f" to change in input for different values of "x".…”

“…However, these authors have not investigated the sensitivity analysis of the network. Another study (Hayward & Cruz-Hernandez, 1998) refers to sensitivity, where the main concern is the behaviour of a mass-springdamper system. Therefore, based on the aforementioned references, the authors could not compare the engineering results for the works mentioned above with the results of the present paper.…”

Haptic Perception of Real and Virtual Curvature

“…The second intuition is that the assembly of two gains in a single curve resembles a saturation plus a gain. This curve is, in essence, an inverse model for a transmission with friction [5]. In fact, points ±τ ba in Fig.…”
