High Speed Cost Effective Simulation and Design Techniques for PEPDS: Basic Research
Abstract
The project will build on the experience gained in the creation of high-speed, real-time and nonreal-time simulations of power electronic and other systems using field-programmable gate arrays(FPGAs). The overall goal of the research is to explore simulation and design techniques for PowerElectronic Power Distribution Systems (PEPDS) that enable system designers to simulate, design,and implement a system using a single representation of the model or algorithm underdevelopment. The research plans to support this goal through three main threads. First, throughthe investigation of techniques for automated and transparent model conversion for directimplementation within an FPGA, which would enable accelerated simulation execution andprovide a final implementation of the model or algorithm. The techniques would enable users toutilize FPGA technology without having expertise in the hardware description languagescommonly used to configure FPGAs. The approach under investigation can be applied to arbitrarymodels and extends the limited capabilities of current design software, which restricts how usersmay define models for direct implementation in FPGAs. Second, the research explores thecommunication among devices in large simulation systems to support high-speed, real-timeexecution across multiple, heterogeneous devices and the integration of these communicationmechanisms into automated model conversion and implementation. Third, research into adaptivecontrol algorithms for systems with time-varying parameters can increase stability of systemsunder study, including linear and non-linear systems. Adaptive control algorithm research alsoprovides a motivating example for evaluation and demonstration of transparent model conversionand communication research outcomes.The outcomes of the proposed research would enable PEPDS designers and engineers to build anddeploy systems with increased stability at a lower design, implementation, and lifetime cost.Transparent model conversion would enable designers to use a single model representation fromdesign through deployment, reducing verification and validation efforts, eliminating costsassociated with implementing models across multiple methodologies, and decreasing design anddevelopment time. High-speed communication research outcomes would enable users to utilizelarge simulation systems, primarily consisting of FPGAs, to decrease simulation execution timeand interface to existing simulation systems or hardware components. Integrating thecommunications into the transparent model conversion process supports the execution ofsimulations across multiple devices without direct input from designers. Improved adaptive controlalgorithms would decrease system maintenance costs and extend system lifetime as controllersadapt to time-varying changes in system parameters.
