摘要:

基于线性二次高斯方法和卡尔曼滤波局部化自适应,提出了一种新的自适应光学系统控制律的算法。它允许处理非平稳行为,以获得性能接近的最优定义的剩余相位方差最小化标准,并减少计算负担与本质上并行实现的极大望远镜(ELTs)。

英文摘要:

We propose a new algorithm for an adaptive optics system control law, based on the Linear Quadratic Gaussian approach and a Kalman Filter adaptation with localizations. It allows to handle non-stationary behaviors, to obtain performance close to the optimality defined with the residual phase variance minimization criterion, and to reduce the computational burden with an intrinsically parallel implementation on the Extremely Large Telescopes (ELTs).
