Group mission

Our mission is to provide engineering solutions in the areas of communications, control and electric power to industrial and societal challenges in order to yield new design concepts, new methodologies and novel control techniques to assist national and international organisations to enhance their communications, control and electric power systems quality with the ultimate objectives of improving systems controllability efficiency, connectivity, security and sustainability.

Our innovative work embraces the following areas of research: control engineering techniques, electric power engineering, communications engineering and seismic data analysis systems.

Please see our list of Research Themes and Activities for further information.

Research Themes

Telecommunication systems-Circuits & Systems, Signal Processing

The research is on design of circuits and systems for communication systems, specifically development of BiCMOS/CMOS based radio-frequency (RF) ADCs and reconfigurable CMOS active RF filters for multi-standard wireless front-end applications and Electronic Warfare systems. In addition, the research investigates design of analogue-to-information converters (AIC) based on Compressive Sensing, design of Cognitive radio and broadband data transfer over power-lines. The research includes microwave research particularly in high-temperature superconducting microstrip bandpass filter design, quasi-elliptic microstrip bandpass filter using tap coupled open-loop resonators and the novel microstrip dual-bandpass filters using dual-mode square patch resonators.

Electric Power & Control

It is expected that electric cars sales will increase dramatically by 2020; the research is focussed on the impact of the high density of electric vehicles charging on low voltage grid in terms of power quality. The research investigates applying robust and optimal control techniques on electric drives to ensure unvarying performance under dynamically changing environmental conditions and optimal control algorithms utilisation to minimise energy consumption. Moreover, it looks at novel electrical machines design strategies to ensure further compactness and enhanced operational efficiency of these machines. It will consider optimal control strategies for solid-state power converters used in active power filters and renewable energy resources. In addition, the research will investigate advanced control algorithms for process industrial control.  

Signal Processing for Seismic Analysis

The research pursues novel methodologies in seismic analysis and instrumentation using signal processing techniques. It engages in the design and construction seismometer instruments for use in seismic zones in order to record and measure translational and rotational, strong ground motion. Such seismometers would be designed and manufactured in the latest silicon state-of-the art nanometer design technologies.

Research Activity

Telecommunication systems - Circuits and Systems, Signal Processing

The Group has introduced novel approaches for predicting the stability of Delta-Sigma modulators for other than DC inputs such as sinusoidal, multiple-sinusoidal for single and multi-bit quantizers. The results of this research would enable the optimisation of the design of higher-order single loop Delta-Sigma modulators with increased dynamic ranges for various telecommunications applications. In addition, the Group has contributed to the European Telecommunication Standardisation Institute (ETSI) standardization efforts on software-defined radio (SDR) and cognitive radio techniques (CRT). The Group is collaborating with the Sensors, Circuits and Systems Group at University College London for the design of a wireless sensing network with integration with 5G and for the design of Compressive Sensing based analogue-to-information converters. Moreover, the Group is collaborating with the University of Birmingham contributed to microwave research particularly in high-temperature superconducting microstrip bandpass filter design and quasi-elliptic microstrip bandpass filter using tap coupled open-loop resonators and the novel microstrip dual-bandpass filters using dual-mode square patch resonators.

Electric Power and Control

The Group has developed novel compensating current evaluation algorithms for power active filters based on orthogonal transformation strategy. This resulted in fast-acting compensating mechanisms to reduce higher harmonic pollution and reactive power with particular applications in railways systems. These algorithms were implemented by a Slovakian based firm in conjunction with the University of Zilina (Professor B Dobrucky) to improve the quality of their active power filters for applications in locomotives and defence industries. Moreover, research was carried out in conjunction with Seoul University (Professor J Song) on the effect of the position of active power filters in railway systems on their performance. Different novel control algorithms corresponding to the installation position of the active power filter at the substation or at the sectioning post have been developed and the merits and drawbacks of each have been concluded. The Group has an EPSRC Case Award in Conjunction with Control Technique Dynamics (£60,000) 2009-2012.

Signal Processing for Seismic Analysis

Since 2008 the Group has been developing new wavelet transform methods, recovering the low-frequency fling from seismic events by removing the baseline error. The research has demonstrated that this error is actually locatable in time. The error is an acceleration transient caused by ground torsions and rotations. These novel results have been made possible by collaborating with colleagues at the University of Bristol (Dr N Alexander), Iceland University, (Professor R Sigbjornsson, Dr B Halldorson) and a spin-off (CUSP Company) from the University of Canterbury, New Zealand under the direction of Dr John Berrill). Moreover, recently the Group is collaborating with Professor Jack Baker's research group (Lynne Burks) at Stanford University in obtaining the low-frequency fling pulses for the particular research. Furthermore, the Group has presented a three-dimensional approach in conjunction with genetic algorithms to investigate the effect of earthquake force inclination on minimum stability factor of safety and the shape & direction of the corresponding failure force which can be integrated into software building constructional design package to provide earthquake-resistant capability.
