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.

数字控制是运动工业的核心，相关算法可以从简单到复杂，动态范围从几微秒到几十秒。执行具有高实时性约束的复杂计算的需求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进展，特定应用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。对于低产量（很少1000），FPGA作为最终平台具有经济优势。对于更高的批量生产，可以将基于fpga的控制器原型的“网表”形式的描述发送到集成电路结构中，作为ASIC蚀刻在硅上。然而，由于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，由于几个因素，包括控制专家难以轻松地使用这些技术，缺乏适合其需求的设计工具，控制算法日益复杂以满足紧急动态，以及难以以ic的形式实现它们，新的挑战正在出现。因此，需要一项研究贡献，以协助在数字控制芯片上的通用系统的发展。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，该技术包括一种简单的设计策略和可重用的硬件核心，这些硬件核心能够很好地适应应用程序的用户和性能标准。FPGA平台将用于支持所提出的技术，目标是实时限制不超过10微秒，同时保持低到中等的逻辑空间，以实现经济高效的解决方案。该贡献的功能和性能将通过一些复杂控制交流驱动器的案例研究来演示。
