利用离散模型参考自适应控制算法来控制大型射电望远镜可以减小摩擦和不确定因素的影响。本文给出了一些现埸试验结果,这些试验是在只保持仰角恒定情况下,方位环路中工作的自适应控制器实现的。初步试验表明,跟踪精度提高了一倍。
Using discrete model reference adaptive control algorithms to control large radio telescopes can reduce the effects of friction and uncertainty. In this paper, we present the results of the present experiments, which are performed by an adaptive controller that operates in the azimuth loop while keeping the elevation angle constant. Preliminary tests show that tracking accuracy is doubled.
