Abstract This work analyzes the use of digital controllers for the temperature regulation of an aeronautical pneumatic system based on discretized nonlinear control laws. The assessed nonlinear control laws are based on feedback linearization, sliding mode and flatness-based control, with a particular emphasis on the noise. Some filtering strategies are proposed, with special attention on the high-order derivative signals. The issue of choosing the sample rate is addressed for each of the control laws. Tests were carried out using a realistic model with the structure validated with the actual experimental data. Nevertheless, some system parameters have been intentionally modified due to industrial confidentiality.

一种用于航空气动系统的非线性数字控制器

摘要 本文分析了数字控制器在基于离散非线性控制律的航空气动系统温度调节中的应用。评估的非线性控制定律基于反馈线性化、滑模和基于平坦度的控制，特别强调噪声。提出了一些滤波策略，特别关注高阶导数信号。每个控制律都解决了选择采样率的问题。使用具有实际实验数据验证的结构的现实模型进行测试。尽管如此，由于行业机密性，一些系统参数已被有意修改。
