Dr Michael Ruppert attended the IEEE Control Systems Society Awards Ceremony at the 2018 IEEE Conference on Decision and Control in Miami, Florida, on December 18, 2018, to accept the Outstanding Paper Award from the journal IEEE Transactions on Control Systems Technology. This journal is widely accepted as the premier scientific journal in control engineering, [...]
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 analysis [...]
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 signal and averaging [...]
Prof Andrew Fleming, A/Prof Yuen Yong and Dr Michael Ruppert from the Precision Mechatronics Lab contributed to securing a $438,000 ARC Linkage Infrastructure Equipment & Facilities (LIEF) grant for A femtosecond laser micromachining facility for a wide range of materials at the University of Griffith. With the benefit of the facility’s unique capabilities, the research [...]
The Precision Mechatronics Lab is showcasing some of their research on Microelectromechanical sytems (MEMS) related to high-resolution atomic force microscopy at the The Art of Problem Solving at the Newcastle Museum. The exhibition showcases UON’s most exciting engineering and computing innovations - like sensor gloves that teach sign language, a heart rate monitor for cows, [...]
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 [...]
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 [...]
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 [...]
Date & Venue Thursday, 04 October 2018, 02:00PM 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 [...]
Date & Venue Thursday, 20 September 2018, 02:00PM EF122 Abstract In this talk, the basic principles of optical design will be explained. Measurement techniques typically used by engineers will be covered. The talk focuses on the practical aspects and will skip most of the maths. A brief overview of the usage of CAD software packages [...]
