simulink问题： update your model with the psbupdate function
当输入simupowersystems/extra library/中的模块时老提示"You are working with an old simupowersystems version 2 model.Please update your model with the psbupdate function."，并且所显示模块无法和其它模块连线，是什么原因呢？怎么解决呢？多谢高手了！！:'( 在help-〉search里输入psbupdate搜一下相关帮助就清楚了，下面是其中的头条Using the psbupdate Command
The psbupdate command converts models built with Version 2 blocks into the Physical Modeling block diagram interface and library of SimPowerSystems 3.1. The conversion happens in three steps: powerlib blocks replace Version 2 powerlib2 blocks. The block ports are sometimes reordered. Physical Modeling connection lines replace Simulink signal lines, if those lines connect the new Physical Modeling electrical terminal ports on the converted blocks. Special JunctionPoint blocks are inserted at line branch points. Subsystem ports are converted, if necessary, to the new Connection Port blocks. See Terminal Ports for the Electrical Domain of Physical Modeling and Special Conversion Blocks and Retired Version 2 Blocks.
The conversion can fail to convert and reconnect some connection lines. See Repairing Incomplete Connection Lines. The psbupdate function changes the name of your model to <oldmodelname>_updated and saves it under this name so you can easily refer to the original model if you need to reconnect broken lines.
