论文摘要
在本文中，引入了一个新的观察者来估计晶体尺寸分布（CSD）仅从溶质浓度，温度和生长速率模型的测量中。不需要成核速率的模型。这种方法基于使用Kazantzis-Kravaris/Luenberger观察者的使用，该观察者指数估计了CSD的功能。然后，通过Tikhonov正则化程序估算完整状态。提供了数值模拟。我们的方法依赖于无限的观察者，这与通常的基于力矩的观察者相反。
In this paper a new observer is introduced to estimate the Crystal Size Distribution (CSD) only from the measurements of the solute concentration, temperature and a model of the growth rate. No model of the nucleation rate is needed. This approach is based on the use of a Kazantzis-Kravaris/Luenberger observer which exponentially estimates functionals of the CSD. Then, the full state is estimated by means of a Tikhonov regularization procedure. Numerical simulations are provided. Our approach relies on an infinite-dimensional observer, contrarily to the usual moment based observers.
