High-performance, fault-tolerant, and energy-efficient control technology

数字控制是运动工业的核心，相关的算法可以从简单到更复杂，动态范围从几微秒到几十秒。需要执行具有高实时约束的复杂计算一直是先进控制器开发的主要技术挑战。由于近年来的重大技术突破以及大规模集成和计算机辅助设计工具领域的持续快速发展，应用特定芯片的实现变得越来越快速和负担得起，使电子系统能够跨越新的性能记录。可重新配置的FPGA现在允许在实验室中快速设计和验证任何SoC。对于低生产量（几千个），FPGA作为最终平台具有经济优势。对于更高的批量生产，控制器的基于FPGA的原型的“网表”形式的描述然后可以被发送到IC结构以在硅中蚀刻为ASIC。然而，随着这些新技术开始用于数字控制以克服迄今为止使用的微控制器和DSP处理器的局限性，由于若干因素，新的挑战正在出现，包括控制专家难以轻松地使用这些技术，缺乏适合于他们需求的设计工具，控制算法日益复杂以满足紧急动态，以及以IC的形式实现它们的困难。因此，需要一个研究的贡献，以协助发展的通用系统芯片的数字控制。为了满足这一需求，本提案的主要目标是设计和开发一种有效的技术，包括一个简单的设计策略和可重用的硬件核心，很好地适应用户和应用程序的性能标准。FPGA平台将用于支持所提出的技术，目标是不超过10微秒的实时约束，同时保持低到中等的逻辑空间，以实现具有成本效益的解决方案。这一贡献的功能和性能将通过复杂控制交流驱动器的一些案例研究来证明。

Digital control is the heart of motion industry, and the associated algorithms can go from simple to more complex, with dynamics ranging from few microseconds to several tens of seconds. The need to perform complex computations with high real-time constraints has always been a major technological challenge for the development of advanced controllers. Thanks to major technological breakthroughs in recent years and sustained rapid progress in the areas of a massive scale integration and computer aided design tools, the realization of application specific chips becomes increasingly rapid and affordable, enabling electronic systems to cross new performance records. The reconfigurable FPGA permits now to design and validate quickly, in laboratory, any SoC. For low production volumes (few 1000s), the FPGA is economically advantageous as a final platform. For higher volume production, the description in the form of "netlist" of FPGA-based prototype of the controller can then be sent to an ICs fabric to be etched in silicon as an ASIC. However, as these new technologies are beginning to be used in digital control to overcome the limitations of microcontrollers and DSP processors used so far, new challenges are emerging due to several factors, including the difficulty for control specialists to work easily with these technologies, lack of design tools adapted for their needs, the increasing complexity of control algorithms to meet exigent dynamic, and the difficulty of implementing them in the form of ICs. The need for a research contribution to assist the development of generalized system on a chip for digital control is therefore felt. To meet this need, the main objective of the present proposal is to design and develop an effective technology that includes an easy design strategy and reusable hardware cores that are well adapted to both the user and performance criteria of the application. An FPGA platform will be used to support the proposed technology targeting real-time constraints no more than ten microseconds while keeping a low to moderate logic space for a cost-effective solution. The functionality and performance of this contribution will be demonstrated through some case studies of complex control AC drives.
