摘要:

提出了一种基于性能的串级控制系统参数自整定方法,对两个控制回路的直线轴驱动运动控制器参数进行联合整定。采用贝叶斯优化,同时调整所有参数,保证了该方法渐近收敛到全局最优的成本。的数据效率和性能的方法进行了研究数值几个培训配置和数值比较,实现与经典的调整方法和详尽的成本评估。在实际系统上,实验比较了标称调谐的跟踪性能和对干扰的鲁棒性。数值研究和实验数据都表明,所提出的自动调谐方法是有效的,在所需的调谐迭代,鲁棒性的干扰,并在改善跟踪的结果。

英文摘要:

We propose a performance-based autotuning method for cascade control systems, where the parameters of a linear axis drive motion controller from two control loops are tuned jointly. Using Bayesian optimization as all parameters are tuned simultaneously, the method is guaranteed to converge asymptotically to the global optimum of the cost. The data-efficiency and performance of the method are studied numerically for several training configurations and compared numerically to those achieved with classical tuning methods and to the exhaustive evaluation of the cost. On the real system, the tracking performance and robustness against disturbances are compared experimentally to nominal tuning. The numerical study and the experimental data both demonstrate that the proposed automated tuning method is efficient in terms of required tuning iterations, robust to disturbances, and results in improved tracking.
