Hi, all
I am trying to recreate a one-mass model of a y-axis feed drive as a sub-system of a CNC machine on Simulink. The model diagram is readily available from research paper, but I can't recognize these transfer function blocks. Are these custom blocks I can build on Matlab? Kp and Tn are supposed to be proportional and integral gains of a velocity controller, respectively; while Te is the electrical drive time constant.
Also, 'Tn.s' means that Tn is a function of s or is this Tn dot s?
Thank you for the help.

Simulink provides Transfer Fcn block in the Simulink/Continuous Library. The Transfer Fcn block models a linear system by a transfer function of the Laplace-domain variable s. The block can model single-input single-output (SISO) and single-input multiple-output (SIMO) systems.
You can add the Transfer Fcn block from the Library Browser under Simulink/Continuous. Provide the numerator and denominator coefficients to the linear system.
Refer to the Documentation for more information.
