ESO NGC，新通用控制器，于2012年在ESO Paranal天文台首次亮相。该控制器从上一代控制器（即ESO IRACE和FIERA探测器控制器）发展了三十多年。NGC是一个控制器平台，可以适应和定制所有红外和光学探测器。最近，NGC也被部署在自适应光学与电子倍增CCD和红外电子雪崩光电二极管阵列。本文概述了使用NGC控制器的应用，并介绍了与控制器实现的检测器性能。由于NGC运行ESO仪器的所有新探测器系统，因此天文台可以使用统一的平台，便于操作和维护。展望了NGC控制器的发展前景。目前为E-ELT研制的高阶波前传感器样机要求在真实的时间控制回路中读取22路200 MHz的LVDS输出。这在高速、低噪声和最小延迟方面提出了新的挑战
The ESO NGC, New General common Controller, had his first light at the ESO Paranal Observatory in 2012. The controller has evolved over three decades from previous controller generations, namely the ESO IRACE and FIERA detector controllers. NGC is a controller platform which can be adapted and customized for all infrared and optical detectors. Recently NGC has also been deployed in adaptive optics with electron multiplication CCDs and infrared electron avalanche photodiode arrays. This paper presents an overview of applications using the NGC controller and describes the detector performance achieved with the controller. Since NGC runs all new detector systems of ESO instruments, a uniform platform is available at the observatory which facilitates operation and maintenance. An outlook will be given of future developments of the NGC controller. The prototype of the high order wavefront sensor currently being developed for the E-ELT is required to read 22 LVDS outputs at 200MHz in real time control loop. This represents new challenges in term of high speed, low noise and minimum latency
