论文摘要
重置控制已成为流行PID的可行替代方案，能够超越和克服线性限制。但是，在运动控制系统中，量化会导致严重的性能降解。本文研究了实用系统中的这种降解，并重新解决了重置频带条件以减轻同样的条件。已经在基于质量的定位系统上进行了数值模拟，以分析量化诱导性能降解的原因。此外，使用建议的解决方案进行了性能和鲁棒性分析。最后，提供了新颖的调整指南，以估算所需的重置谱带参数。另外，在高精度运动系统上进行了实践实验以进行验证。实验表明，复位频带可以将有问题区域的误差减少多达285％，因此显示了所提出的解决方案的需求和有效性。
Reset control has emerged as a viable alternative to popular PID, capable of outperforming and overcoming the linear limitations. However, in motion control systems, quantization can cause severe performance degradation. This paper investigates this degradation in practical systems and re-purposes the reset band condition in order to mitigate the same. Numerical simulations have been conducted on a mass based positioning system to analyze the cause of the quantization induced performance degradation. Moreover, a performance and robustness analysis was performed with the proposed solution. Finally, novel tuning guidelines are provided for estimating the required reset band parameter. Additionally, practical experiments have been conducted on a high precision motion system for validation. The experiments show by example that the reset band can reduce the error in the problematic region by up to 285% and hence shows the need and effectiveness of the proposed solution.
