使用控制定律主动降低电机的噪音和振动 - HAL 开放档案
Source: theses.hal.science
Article summary:
1. This thesis focuses on the development of powertrains for electric vehicles, with a particular emphasis on noise and vibration issues.
2. The aim is to develop control laws dedicated to reducing currents harmonics that cause vibration harmonics.
3. Two different control laws are proposed and tested: one based on H-infinity optimization and one based on an external disturbance observer.
Article analysis:
The article is generally reliable and trustworthy, as it provides detailed information about the research conducted in the context of developing powertrains for electric vehicles, with a focus on noise and vibration issues. The article also outlines two different control laws that have been proposed and tested in order to reduce current harmonics responsible for vibration harmonics.
However, there are some potential biases in the article that should be noted. For example, the article does not provide any information about possible risks associated with using these control laws or any counterarguments to their use. Additionally, the article does not present both sides of the argument equally; instead, it focuses solely on presenting the benefits of using these control laws without exploring any potential drawbacks or limitations. Furthermore, there is no evidence provided to support the claims made in the article regarding the effectiveness of these control laws in reducing current harmonics and corresponding vibration harmonics.
