A self-resonant MEMS-based electrostatic field sensor
2006 American Control Conference, 2006Co-Authors: Kent H. Lundberg, J. Shafran, Jinbo Kuang, M. Judy, T. DenisonAbstract:An electric-field sensor is presented for applications such as Xerography. The sensor combines a vibrating MEMS structure with synchronous-detection electronics. The sensor architecture has three major blocks: a MEMS shutter, a sense interface, and a self-resonant drive loop that feeds back to the MEMS shutter. The self-resonant feedback loop is the enabling technology that provides the improved performance reported here. Prototyped in the iMEMS3 process at Analog Devices, the noise floor is 4.0 V/m/radic(Hz) and the integral nonlinearity is 20 V/m over a range of plusmn700 kV/m, which is an order-of-magnitude improvement over existing MEMS devices

A Self-Resonant MEMS-Based Electrometer
2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007, 2007Co-Authors: Timothy A. Denison, Jinbo Kuang, John S. Shafran, Kent H. LundbergAbstract:A configurable MEMS electrometer that allows for isolated, high-input-impedance voltage measurements is presented. By adjusting the separation between the measurement surface and a vibrating MEMS element, the noise floor and/or maximum dynamic range can be tailored to the specific application. This device is useful for a broad range of applications, including pH meters, biopotential amplifiers, Xerography, and measuring leakage on high-voltage capacitors.

Constraint Management of Rotating Machinery With Application to Xerography
2019 American Control Conference (ACC), 2019Co-Authors: Hamid R. OssarehAbstract:This paper is concerned with the problem of constraint management for rotating machinery with actuators and sensors fixed in inertial space. Such systems arise in Xerography, drilling and milling machines, and turbo machinery. The proposed approach consists of first discretizing the rotating device spatially and temporally to obtain a discrete-time lumped linear periodic model of the rotating device. Linear tracking controllers are then designed to stabilize the system, followed by the application of the Reference Governor (RG) technique for constraint management. To accomplish the latter, we extend the earlier results in the literature of RG to the case of periodic systems with disturbances, which arises in applications. We illustrate the theory using a numerical simulation of the fusing stage of a xerographic process.

Modeling and control of color xerographic processes
Proceedings of the 38th IEEE Conference on Decision and Control (Cat. No.99CH36304), 1999Co-Authors: R. Groff, T. Thieret, P. Khargonekar, D. Koditschek, L.k. MesthaAbstract:The University of Michigan and Xerox's Wilson Research Center have been collaborating on problems in color management systems since 1996, supported in part by an NSF GOALI grant. The paper is divided into three sections. The first discusses the basics of Xerography and areas where systems methodology can have a potential impact. The second section describes the authors' approach to the approximation of color space transformations using piecewise linear approximants and the graph intersection algorithm, with a brief review of some of the analytical and numerical results. The last section expounds on some of the benefits and difficulties of industry-university-government collaboration.

Toward a control oriented model of xerographic marking engines
Proceedings of 35th IEEE Conference on Decision and Control, 1996Co-Authors: L.k. Mestha, Y.r. Wang, S. Dianat, E. Jackson, T. Thieret, P.p. Khargonekar, D.e. KoditschekAbstract:This paper presents some preliminary results from a research collaboration concerning the modeling and control of color Xerography. In this first communication of our work, we describe our efforts to develop a model for a monochrome marking engine. We adopt the technique of principal component analysis for choice of output coordinates and demonstrate preliminary experimental evidence suggesting that this procedure yields accuracy in data reconstruction superior to present industry practice. Preliminary analysis of the experimental evidence suggests that the process has a nonlinear component that we seek to model using a mixture of physical and empirical insight.
