This model demonstrates how a current controller for a DC PM drive works.
The current controller is parameterized according to the absolute optimum.
At time=0.2 s a reference torque step is applied, causing the drive to accelerate until motor torque and load torque are at an equilibrium.

This model demonstrates how a speed controller for a current controlled DC PM drive works.
The inner current controller is parameterized according to the absolute optimum. The outer control loop is formed by the speed controller which is parameterized according to the symmetrical optimum.
At time=0.2 s a reference speed step is applied, causing the drive to accelerate to the desired speed. At time=0.8 s a load torque step is applied, causing to drive to decelerate until the speed controller brings the drive back to the desired speed.
You may try a slewRateLimiter instead of the prefilter to limit the speed rise i.e. the torque.

This model demonstrates how a position controller for a speed controlled DC PM drive works.
The inner current controller is parameterized according to the absolute optimum. The middle control loop is formed by the speed controller which is parameterized according to the symmetrical optimum. The outer control loop is formed by the position controller which is parameterized to avoid an overshot in the position.
At time=0.2 s the kinematicPTP starts to prescribe the reference position with limited speed and limited acceleration. At time=2.3 s a load torque step is applied, causing to drive to slightly leave the end position until the position controller brings the drive back to the desired position.
