The necessity of an integrated view of the process has found a first response in software engineering techniques. The application of formal methodologies, as Petri Nets, for software specification allows testing and validation of time constraints. The compliance with IEC 1131-3 standard plays a key role in software design and suggests the utilisation of the graphical language Functional Block Diagram (FBD). A new approach, funded by the European Community under the ESPRIT Project INFORMA, is presented. In particular INFORMA develops an integrated toolbox for designing, simulating, and analysing embedded (hybrid) systems, where the digital controller and the analog embedding are strictly connected. An example of electrical drives application based on a synchronous machine fed by a cycloconverter is then presented to exemplify the new methodology.","PeriodicalId":250682,"journal":{"name":"COM.P.EL.98.

The discrete-level sinewave approximations described in this paper can be implemented with reduced switching losses, in comparison to typical pulse-width modulation patterns, and with user-selectable harmonic content. We present two design algorithms, including an algorithm based on simulated annealing. The algorithms allow the engineer to select switching sequences that meet desired objectives or characteristics in almost any context. In addition, we demonstrate the use of these sequences experimentally in a practical application.","PeriodicalId":250682,"journal":{"name":"COM.P.EL.98.

In the past, special test cases have been used to emphasize the strengths of a new control technique and show the weaknesses of conventional approaches. It can be debated whether these test cases are realistic. This paper proposes a suite of benchmark converters that are examples of good conventional designs. The benchmark designs are based on the extensively studied methods of averaging and linearization. The benchmarks are proposed as reference circuits for comparisons of simulators and control methods.","PeriodicalId":250682,"journal":{"name":"COM.P.EL.98.
