State machine for grid connection – TIDM-SOLARUINV
Hi,
I hope everything is going well. I have a question regarding using MATLAB to write code for the C2000 controller – F28035. I am currently implementing the TI Microinverter (TIDM-SOLARUINV) controlled by the F28035 using MATLAB. I have tested the input side MPPT and the output side inverter and grid integration.
However, I am uncertain about how to integrate both the PV and inverter together for grid integration. TI has used a state machine for grid connection as described on page 45 of the documentation (https://www.ti.com/lit/ug/tidu405b/tidu405b.pdf?ts=1716863482444&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FTIDM-SOLARUINV). Could you please provide some guidance or an example file on how to implement this in MATLAB? Your assistance would be greatly appreciated.

How do I display all the data, not just the last 30 minutes or so
I am collecting data every minute or so (for now while I debug my system). How can I display all the data instead of the last few minutes?
I know I can download all the data and plot it in Excel or LibreOffice but I would prefer to be able to see more of the data on the graph, like at least a day. I see examples like the chart of air pollution that has A LOT of data points, but I do not know how it’s done.

How to efficiently use dependent properties if dependence is computational costly?
Hello!
I want to design a class where some properties are dependent on others. I understand the general concept of Matlab OOP for dependent properties: the property is recalculated each time it is accessed.
But if these calculations/dependencies are costly and the dependent properties are often accessed by methods within the class, what are you suggesting to do. Basically, it would suffice to recalculated the property each time its parents properties are updated.
If I do so, I get a warning that accessing another property from the set method of an independent property is not recommended. What else can I do?
Cheers

Problem with anfis CLUSTERING
Hello all,
I am trying to use genfis2 to create a FIS structure to be used by ANFIS. I am working with a set of data that is 3000×3. The first 2 columns are the inputs for genfis2 and last column is the output. Below is how I am using the genfis2 command,
in_fis = genfis2(Xin,Xout,radii)
from what I understand, radii is a vector that determines the range of a cluster and xbounds are the min/max (to normalize the data) values in each column of data correct? Why am I getting
"Warning: Rank deficient, rank = 0, tol = NaN.

Time response of modes to an impulse

I have 2 roots of the plant matrix for both short period mode and phugoid mode and corresponding period times. How can I plot the responses of the 4 variables with specified initial conditions for an elevator angle deflection?
