Can the integration method be changed for discrete PI controller block from motor control blockset?

I am using Discrete PI controller block from recently released motor control blocket toolbox. It seems like the default Integrator method is set to "Acuumulator: Forward Euler". Is there a way to change integrator method to Backward Euler or trapezoidal?

[Fangjun Jiang]

which block?

[Prathamesh Vadhavkar]

"Discrete PI Controller" block. Its part of of the Motor Control Blockset toolbox.

It does not have that option from this link. https://www.mathworks.com/help/mcb/ref/discretepicontroller.html?s_tid=srchtitle

are you looking under masks?

[Prathamesh Vadhavkar]

Yes, I was looking under the mask to figure out what the default integrator type is. That is how I found out that it is set to Accumulator: Forward Euler.

A DiscreteIntegrator block has that option. You just have to change it yourself if it is available. Of course then you will be deviated from the built-in Motor Control Blockset Library.

Or you can contruct it yourself from the DiscreteIntegrator block.

I realize that I can use other block or build my own. In my opinion its kind of a miss to not have that oprion in this particular block. Hopefully Mathworks will add that in future.
