摘要
电力电子系统发展迅速,因此需要有效的原型开发方法,以便在硬件实施之前测试控制算法和评估系统性能。本研究提出了一种基于模型在环 (MIL)、软件在环 (SIL) 和处理器在环 (PIL) 方法的完整原型开发策略,适用于使用 TI F28069M Launchpad 套件的反激式转换器。这些技术可结合使用,以准确快速地评估控制策略,从而加快设计周期并提高系统可靠性。本作品介绍了所建议的原型验证平台,并对每个原型验证阶段及其相关优势进行了详细说明。实验结果分析并显示了针对 50W 额定功率反激式转换器所建议的方法在快速算法开发、系统仿真、实时控制实现和控制器设计精度方面的有效性。结果表明,反激式转换器的设计控制器在参考电压跟踪的过冲和沉淀时间方面的性能与 MIL 和 SIL 实现几乎相同。另一方面,在 PIL 实现中,控制器的过冲性能比 SIL 和 MIL 实现多偏差 1.18%。这也证实了反激式控制系统在所有开发阶段的性能都是可靠和有效的。
MIL, SIL and PIL Implementation for Closed Loop Control of Flyback Converter
Power electronic systems are rapidly evolving; thus, effective prototyping methods are required to test control algorithms and assess system performance prior to hardware implementation. This research suggests a Model-In-The-Loop (MIL), Software-In-The-Loop (SIL), and Processor-In-The-Loop (PIL) methodologies-based complete prototyping strategy for flyback converters using the TI F28069M Launchpad kit. These techniques can be combined to evaluate control strategies accurately and quickly, speeding up design cycles and enhancing system reliability. The proposed prototyping platform is presented in this work, along with a thorough explanation of each prototyping stage and its associated advantages. The effectiveness of the suggested approach for 50W rated power flyback converter in terms of quick algorithm development, system simulation, real-time control implementation and controller design accuracy is analyzed and shown by experimental results. The results show that the performance of the designed controller for the flyback converter is almost the same as in MIL and SIL implementation in terms of the overshoot and settling time in the reference voltage tracking. On the other hand, in the PIL implementation, the overshoot performance of the controller deviates by 1.18% more than in SIL and MIL implementation. These also confirm that the flyback control system's performance is reliable and effective during all phases of development.
