About Michael Ruppert

Michael Ruppert received the Dipl.-Ing. Degree in automation technology in production, with a specialization in systems theory and automatic control, from the University of Stuttgart, Germany, in 2013. In 2017, he received the Ph.D. degree with excellence award in Electrical Engineering from The University of Newcastle, Australia where he is now a Postdoctoral Research Associate with the School of Electrical Engineering and Computing. His research interests include the control, estimation and self-sensing of microelectromechanical (MEMS) systems such as piezoelectric microcantilever and nanopositioning systems for multifrequency and single-chip atomic force microscopy.

Special Session on Micro and Nano Precision Mechatronics at the 2019 MARSS Conference, Helsinki, Finland, 1-5 July 2019

Join us at a special session at the 2019 International Conference on Manipulation, Automation and Robotics at Small Scales (MARSS) conference, with the goal of bringing together researchers and engineers to advance the state-of-the-art in design and control of micro and nano precision mechatronic systems. The sessions will focus on novel mechanical designs, dynamic […]

Arnfinn Eielsen: Dithering Techniques: New Results and Applications

Date & VenueMonday, 21 January 2019, 01:00pmEF122

Abstract   In non-linear systems where some form of averaging is present (inertia) or can be introduced (low-pass filter), it can sometimes be beneficial to purposefully introduce an additional noise or disturbance signal. This signal is known as dither, and the combination of a dither […]

Mark Balenzuela: Accurate Gaussian Mixture Model Smoothing using a Two-Filter Approach

Date & Venue
Tuesday, 04 December 2018, 11:00am
EF122

Abstract
Gaussian Mixtures (GMs) can be used as a universal density approximator. As such, they can capture multimodal, skewed, and heavy-tailed characteristics of densities describing dynamic behaviour, which appear throughout finance, robotics, and fault detection. In this seminar, we consider smoothing for a class of state-space models where linear […]

Jarrad Courts – Larger Scale Nonlinear State space System Identification

Date & Venue
Thursday, 01 November 2018, 02:00PM
EF122

Abstract
System identification for large scale continuous time nonlinear state space models, as common in mechatronics applications, remains a challenging task. Existing system identification methods can be deficient for complex nonlinear problems and computationally do not scale well on large problems, the focus of this work is to alleviate […]

David Harcombe – Nanoscale Demodulation and Sensing

Date & Venue
Wednesday, 17 October 2018, 02:00PM
EF122

Abstract
Conventional high-speed amplitude demodulation techniques are compared and shown to be incompatible with multifrequency atomic force microscopy (MF-AFM), due to a lack of sensitivity to multiple frequency components. Novel model-based methods including a Kalman and Lyapunov filter are proposed, which alleviate this issue while maintaining very high bandwidths. Additionally, mass-sensing through microcantilever resonance […]

Nathan Bartlett – Multi-Extended Target Tracking

Date & Venue

EF122

Abstract
Extended targets are targets which potentially generate more than one measurement per time step. They are encountered in numerous applications, spanning from vehicle tracking with automotive radar, pedestrian tracking using laser range sensors, and surface vessel tracking with marine X-band radar. The generation of multiple measurements per time […]

Omid Tayefeh – Exposure Planning for Scanning Laser Lithography

Date & Venue
Friday, 31 August 2018, 10:30AM
EF122

Abstract
Lithography is the process of selectively exposing optically sensitive materials during semiconductor fabrication. One issue with standard projection lithography is the high cost of infrastructure and mask sets. These costs may be prohibitively expensive for prototyping and low-volume production. Scanning-beam lithography methods are attractive alternatives to projection lithography […]
