Hello Everyone,

I would like to perform the cross correlation function (crosscorr (y1,y2)) for my data but donot have the Econometrics Toolbox to compute this. Can someone in here help me to get this toolbox or else show me where I could get one?

many thanks, Tobias

Hi. I'm new to matlab. I'm a hobbyst, not a company or anything like this. I brought MATLAB personal with some modules and I'll use to learn FPGA with ZedBoard + AD9361. I know that this board (both) are supported by simulink and I'll test/learn using simulink and block-design. My plan is to make an FM transmitter (for start) when my boards arrive (already brought, still waiting delivery). After that, my plan is to make an receiver and then, do the same receiver, but using another frontend (including ADC). So my question is: imagine that I have plugged in another ADC into my ZedBoard (let's say AD9226), is possible to read this ADC in simulink, like AD9361 does? If yes, how? Where can I find any article or tutorial about this?

Even further: if I want to generate HDL code in the future (using HDL Coder), how can I integrate this 'custom' AD for code generation?

PS: I know that I can't buy HDL Coder for personal. My plan is to use trial for testing, since I'm using just for learning.

Thank you.

I am trying to design the outer voltage loop of the inverter but i am unable to remove the 5,7th harmonics from the capacitor voltage as i am trying to supply nonlinear load. The file is in matlab2018b.

1.When I am trying to code my TMS320F28379D for running a three phase grid tied plant as per the attached image a scope in "SYNCHRONOUS SYSTEM " is showing perfect result but the result is not getting transferred to the "PI_Controller_ISR ".I have concluded this after I have connected the scope at the signal which is entering the "PI_Controller_ISR " subsystem (Inside the subsystem). I am trying to do this in MATLAB 2018B AND F28379D LAUNCHPAD.I am attaching the MATLAB fILE with this help request.Kindly resolve the issue. 2. I have been working on how to send the ADC signal from the C2000 MCU to the Host by seeing the video of** f28379D_DCDC_Buck** in external Mode, but when I downloaded the file and tried to run it by setting the parameters in the HARDWARE IMPLEMETATION pane it is showing me the error message. " Error evaluating 'InitFcn' callback of C28x SCI Receive block (mask) 'c28379Dpmsmfocdual_cpu1_ert/Serial Receive/SCI Receive'.

Kindly resolve these issues.

Please send me some plant digital twin simulink model for productive maintenance.

i want to model LI+ battery , i referred to matlab model https://www.mathworks.com/matlabcentral/mlc-downloads/downloads/submissions/36019/versions/29/download/zip but not able to understand how to make simscape battery parametrs(like R C ), anybody can help ??

Determining State of Charge

Hi, How to represent a transfer function (TF) of a compensated system in MATLAB to plot the bode plot of it, without expanding the denominator? The TF is: T(s) = (1 + s/Wz) / ( (1 + s/Wp) * ( 1 + s/Wo + s^2/W0^2 ) )

I am simulating the attached paper on modulated model predictive control. I have done everything as in the paper. Can some please tell me about my mistake? I am so frustrating since two weeks. Thanks&Regards, G.Sivakumar.

please, I want to use the finite difference method to discretize the telegraphic equations, and then write a matlab code to observe the propagation of a pulse on a transmission line. Help me please

Hello everyone,

      Recently i started using MATLAB Real Time Code Generation Tool to generate code for 3 phase Induction motor speed control using V/F. I used the piccolo launchpad F28027 to implement this V/F technique. I used a pot to get the frequency input and computed the corresponding Voltage using V/F ratio. When i tried implement it on the board, output PWM frequency was not exactly the same which i simulated. It was 2 - 3 times higher than the actual. So i tried reducing the inputs by the same 2-3 times. It worked. 
       Question is, what the problem with the code and processor?  why difference in PWM frequency between simulation and Realtime?

I sent a lot of tech support requests...read excellent advice and caveats...but that does not cook rice, as they say in Korean! It is hard for me to believe that the videos posted and examples cited are carried out with simulations taking hrs and hrs...mine took 3 hrs to do the outer voltage loop estimates from 10 Hz to 5kHz. Sampling time was.2 usec for a converter switching at 50 kHz. Anything less gives awful results. It is certainly the calculations from 10 Hz on to several hundred Hz at 200ns rate that take all this time. Why not post in the examples/ videos run times ...caveat that with the machine on which it was run? It is totally impractical to maintain that the tools cannot be predicted to be run fast, no matter the complexity of the problem at hand. I wish there was a "tool" that could grind through a model & give out in a scheduled simulation times with computing machine parameters! Those that are referenced in tech support documents really do not come close to such clarity. In short, the question of great importance to us: what to do to reduce simulation times to <few minutes from 180 min so that the entire system can be modeled, optimized, retuned & then taken to embedded coder stage for coding. This will bring up totally other realtime run issues...and we need to hurry! Can someone give examples of simulating Active_PFC or any other model through PID Estimates/tuning from 10Hz to 10kHz or 15 kHz in less than a few minutes?..Whatever the machine, toolbox selected to achieve that is what we are looking to test with It is a fact that we always have to be carried on the shoulders of giants so we can see far out there with possibilities... Hoping to hear from someone. robin
