论文摘要
已知重置控制能够胜过PID和类似线性控制器。但是，在运动控制系统中，量化会导致严重的性能降解。本文显示了时间正则化以减轻重置控制系统中这种实际问题的应用。已经进行了数值模拟，以分析量化诱导的性能降解的原因以及时间正则化的有效性以减轻这种降解；还提供了有关时间正则化参数的调整指南。此外，还进行了鲁棒性分析。该解决方案还可以在高精度运动系统上进行实验测试以进行验证。通过数值模拟估计，时间正则化可以将量化诱导的性能降解减少近10 dB。实验类似地显示了高精度运动阶段的几个DB的降低。
Reset control is known to be able to outperform PID and the like linear controllers. However, in motion control systems, quantization can cause severe performance degradation. This paper shows the application of time regularization to mitigate this practical issue in reset control systems. Numerical simulations have been conducted in order to analyze the cause of the quantization induced performance degradation and the effectiveness of time regularization to mitigate this degradation; with tuning guidelines for the time regularization parameter also provided. Moreover, a robustness analysis is performed. The solution is also tested experimentally on a high precision motion system for validation. It is estimated by numerical simulations that time regularization can reduce quantization induced performance degradation by almost 10 dB. Experiments have similarly shown a reduction of several dB for the high precision motion stage.
