Chattering Attenuation Disturbance Observer for Sliding Mode Control: Application to Permanent Magnet Synchronous Motors

IEEE Transactions on Industrial Electronics, 2023
In existing sliding mode control (SMC) methods, a disturbance observer (DOB) is employed to achieve disturbance rejection and reduce chattering, which is a major disadvantage associated with SMC and increases with increasing switching gain.

Chattering Laptops

2008
Mobile computer users often have a false sense of anonymity when they connect to the Internet at cafes, hotels, airports or other public places. In this paper, we analyze information leaked by mobile computers to the local access link when they are outside their home domain.
