Old Wild West Mining Town Railroad Models

Miners worked for months on end often with nothing or very little to show for their efforts. There were a few women and children in the mining communities so a church, or school house would not look out of place for those modeling a mining town or wild western town buildings using printed paper models downloaded from modelbuildings.

Disturbance Observer

For the Permanent Magnet Synchronous Motor (PMSM) control system of the Mine Traction Electric Locomotive (MTEL), the fluctuation of the load will lead to the resonance of the velocity of the MTEL. In addition, the speed sensor is easy to be damaged due to the moisture, dust, and vibration. To solve the above problems, a disturbance observer-based (DOB) backstepping
