Another current topic is identification using continuous-time models, which offer particular challenges in the presence of noise. Within controller design , we have studied various aspects of digital control. The objective is to develop and analyse digital controllers and their interplay with continuous-time processes. Applied research in automatic control is important in achieving an overall high plant performance. An improved control and optimization of waste water treatment plants lead to increased pollutant removal, a reduced need for chemical treatments and energy savings.
Current research includes development of new improved control strategies and design of estimators.
The activities within Nutek s research program in Digital Communications have proceeded well. Within the subject area of signal processing, we have also an extensive work on algorithms for radar signal processing and imaging . The systems analysis team of our group has played an important role for many researchers at Uppsala University and the Swedish Agricultural University, as up to now about 400 researchers and PhD students have attended the PhD courses in systems analysis. The research activities in system analysis have been very successful and have a good international reputation. Within biomechanics, the research mainly concerns gait analysis with applications in orthopaedics and rehabilitation.
