The IOPT-Flow Modeling Framework Applied to Power Electronics Controllers

Abstract
En 中文
The input-output place-transition (IOPT)-flow modeling framework was created to support the design of mixed embedded system controllers containing both reac-tive and data-driven parts, combining Petri net and dataflow elements. The reactive parts, whose evolution depends on external events, are modeled using Petri nets. Data manipu-lation operations that process input signals and events are expressed using dataflows. The framework is composed by a Web-based tool-chain including a graphical editor, a sim-ulator, and automatic code generation tools to produce C and VHDL controller implementations. To demonstrate the language and the related tools, an example of a closed-loop brushless dc servo motor controller is presented. A prototype using the automatic generated VHDL code was implemented on a field-programmable gate array (FPGA) board.
