Hi all, Anyone can help me on this?. I'm developing genetic-fuzzy control for a vehicle system. I need to optimize the fuzzy logic control using GA. At the moment I'm using Genetic Algorithm Toolbox (GAT)for MATLAB developed from Sheffield Uni UK, Simulink and MATLAB m-files. My question is, instead using that GA toolbox, can I just use th
accuracy problem in simulating discrete/continuous mixed model in simulink

hi all, i'm haveing an issue regarding the setting to simulate a discrete/continuous mixed model (continuous time delta sigma modulator) in simulink, particularly when i introduce excess loop delay (in continuous time) in the feedback. when i use different types of solvers, different max step size and different loop delays, the results are significant different from each other. ...

Hello .. I have a major problem when trying to calculate the Exact SNR from the received symbols. Usually, in Simulink it is pretty simple to calculate the SNR per symbol by calculating the variance of the difference between transmitted and received symbols. This works perfect for the ZF receiver. However, for the ML receiver, this method is not possible any more bcuz the ML receiver map...

Modifying the Max step size in function of the time in Simulink

Hi, I am trying to run a Simulink electrical simulation that requires very high precision at certain times during the simulation. The problem is not to set the precision at high level, this can be done easily by changing the Max step size to a very low value. (I have found the value that is required for my simulation.) But by doing this, a memory problem appears, I need to simulate for a...

Hi all I have asignal sample at 27Mhz (jittered clock). I want to process the signal with a jitter free clock. So what shold be the clock freq at which i shold resample the signal. How do i resample an already sampled signal. If i want to say hold the sampled signal and then again resample with saome different clock, how do i modell all this in simulink.Need suggestion ASAP. Thanks & Regard...

Hello, Here is what I have to do: 1. Get a live signal in Simulink using a sound card / dSPACE card 2. Using band pass filters, obtain band BF1,BF2,...,BFn 2. Calculate the sound level from each BF1,...,BFn. 3. Repeat this until an outside / hardware signal is get. Thank you for your time and help. Regards, D.P.

Hi all, I met a problem in Embedded Matlab function. It seems that this customrized block does not support frame based signal. And according to the manual online, it is said "Simulink frames are not supported. However, you can use the Rate Transition block to convert frames into vectors." I can not understand it. Does that mean I can not use the batch processing? So this Embedded Ma...

Hi I'm tring to make an "if" statement over a [512*2] matrix generated from the "from wave device" block in simulink. but I don't know how to make the comparition between the matrix elements and an scallar, because it seems that the "if" block only accepts scalers not matrices or vectors. any answer will be appreciated.

Hi, I'm doing a project of single phase multilevel h-bridge inverter using the simulink. If i'm using the igbt block, and switching using the pulse generator instead of PWM generator, how should i setting the triggering time to get the good sinusoidal output. And also, can I use the universal bridge instead of IGBT block and how to use it since I'm very new to the MATLAB Simulink.
