本文针对一类离散非线性系统,在单输出情形下,提出了一种扩展的类Luenberger观测器。第一点。我们定义了所谓的一致可观测性结构,并给出了相应的标准形。接下来,我们使用这个标准型设计一个简单的观测器的极点配置技术的基础上。最后,我们将观测器应用于生物反应器,并给出了仿真结果。
In this note we present an extended Luenberger-like observer for some class of discrete-time nonlinear systems in the single-output case. First of all. we define the so-called uniform observability structure and give an associated canonical form. Next we use this canonical form to design a simple observer based on the pole placement technics. Finally we apply the observer to a bioreactor and we present simulation results.
