One way to optimize the operation of chemical systems consists on using closed loop controls while the system is operated. This way, it is possible to optimize the operating point in the plant, process or chemical system so that certain quantities are maximized/minimized or time responses are reduced. In the design of the closed loop controls, though, one of the problems is the large number of configuration parameters involved and the uncertainties in the system. The objective of this paper is to present how recently proposed controls, exploiting time-scale separation, allow to configure their closed loop configuration parameters from open-loop measurements. These controls have been proposed to accelerate the time response of metal-oxide gas sensors by operating at constant surface potential. The main result of the paper explains the link between the open loop measurements and closed loop operation. Experiments are provided using a commercial off-the-shelf Microelectromechanical gas sensor.

优化化学系统运行的一种方法是在系统运行时使用闭环控制。这样，可以优化工厂，过程或化学系统中的操作点，以便最大化/最小化某些数量或减少时间响应。但是，在闭环控制的设计中，问题之一是涉及大量的配置参数以及系统中的不确定性。本文的目的是介绍利用时标分离技术，最近提出的控制如何允许通过开环测量来配置其闭环配置参数。已经提出这些控制以通过在恒定的表面电势下运行来加速金属氧化物气体传感器的时间响应。本文的主要结果解释了开环测量和闭环操作之间的联系。使用市售的微机电气体传感器进行实验。
