LINEAR MOTOR GENERATOR MODEL

Hi, Currently modelling an reciprocating engine coupled to a linear PMSM motor/generator for my PhD. I have downloaded the "Model File Package for Motor Control Design Public Video" simulink model.

Is it possible to convert to rotational PMSM simscape plant model used for a linear PMSM model? As there are none in the library to just drag into the existing control model.

Any ideas i can represent a linear motor based on this existing control model?

My output from the machine needs to be linear position w.r.t, with a total stroke of approximately 100 mm. Can i convert the rotational constant speed input at port "W" to a sinusoidal velocity profile (such that it replicates the velocity profile of a linear machine)?

Any help would be great.

Thanks

There is a new PMLSM block from Simscape Electrical in MATLAB R2020a. Here is the link to the block's documentation page: https://www.mathworks.com/help/physmod/sps/ref/pmlsm.html.

Using this block, you should be able to substitute the rotational PMSM plant model with this linear one.

Thanks Zhao.

Have upgrading to 2020a and now have access to the PMSML block.

Thanks for your help
