Modelling, Design and Implementation of D-Q Control in Single-Phase Grid-Connected Inverters for Photovoltaic Systems used in Domestic Dwellings.
… Time-variant systems are more difficult to control than time-invariant systems. Nevertheless, by using suitable transformation techniques, time-variant systems can often be modelled as time-invariant systems. After the transformation, the control signals that are usually time-variant (often …

Application of field programmable analog arrays (FPAAs) to fast scanning probe microscopy
… of implementation in developing fast and robust controllers for an Atomic Force Microscope (AFM) unit. Atomic Force Microscopes (AFMs) are getting faster. However, video-rate imaging still remains a big challenge to the AFM community. Therefore AFMs are required to have very fast nanopositioning …
