Overview Research Topics
The long term objective of the department is the realization of the IMMI project (Interpretation by Measuring, Modelling and Identification), since 1989. Beside this main project, which covers a broad spectrum of several related activities, also some other independent research topics are at stake.
Data-driven signal processing using the nuclear norm heuristic
Applications in signal processing and control theory are typically model-based and proceed in two steps. In the 'modeling' step, a mathematical model is built from the measured noisy data. In the 'design' step, the model is used to solve a specific application problem. In this project, we will...
Carrier aggregation intermodulation distortions in Advanced Systems
Achieving greater throughput in telecommunications requires increasing bandwidth. However, due to scarcity in carrier frequencies, the required bandwidth may not be available in a contiguous band. LTE Advanced uses multiple bands for one single user, which is known as carrier aggregation [1...
Identification of time-varying biomechanical systems
This project aims at extracting models of human joints in a data driven manner. This is done in collaboration with the biomechanics group at the TU Delft, where experimental setups have been instrumented to apply force and position disturbances to joints (ankle, wrist and shoulder). Based on...
BLA-based Design and Analysis of VCO-based Sigma-Delta Modulators
Nonlinear system theory is involved. The available theoretical frameworks depend on the assumed system properties and the applied signals. An example is the Volterra theory framework which uses a series expansion of the system’s behaviour around an operating point. This operating point can be...
Linear parameter-varying modeling and decentralized fault diagnosis for large sets of interacting subsystem
Fault Detection and Isolation (FDI) systems aim at the early detection and localization of faults. They are the key for the establishment of condition-based maintenance on industrial processes, which allows for cost reduction, and a safer and more reliable operation. The research on FDI has been...
Model driven design and characterization of microwave systems
In the development of the 5G communication technology, there is an exponential increase in applications and devices. The 5G standard brings higher data rates, a lower latency and a higher reliability to the end users, resulting in the need for more bandwidth. As a result, designers face many...
