AI Thread Summary
The discussion focuses on methods for controlling a permanent magnet synchronous generator (PMSG) with an emphasis on direct torque control. The user is currently implementing a modified direct torque control (DTC) scheme originally designed for induction motors but is facing challenges, particularly with state estimation. They seek alternative resources or insights, as most information is found in inaccessible IEEE papers. The user notes that many modern wind turbines successfully utilize such control methods. Understanding the relationship between torque and power output at constant speed is crucial for effective PMSG operation.

I'm trying to find some information on different methods of controlling a permanent magnet synchronous generator, more specifically controlling the torque directly. I've done many searches but the only source of information I can find is from papers in the IEEE database which I don't have access to.

I am currently doing this with a modified DTC scheme made for induction motors, however it is not working very well especially the state estimation part. If anyone has some info on how to do this it would be greatly appreciated. I know its possible since many modern wind turbines do this.

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
