Hello Ash B, In MATLAB with R2020b, there is some modification in "to workspace block". You have used variable "simout" and it is storing it in "out.simout". You are required to extract it by command "simout = (out.simout)". Now you can access this variable to do necessary operation.
@@info4eee I was trying to recreate this :ua-cam.com/video/t4XFJkQhMkc/v-deo.html&ab_channel=rkarthikkumarACADEMY After that command it says in orange: Warning: Unrecognized field name "simout". > In Simulink/SimulationOutput/get In Simulink/SimulationOutput/subsref
The reason for problem with plot(t,I) will be the variable t and I. The data in these variable should be in array form for proper working so please select array in workspace block. I hope it will solve your problem. If still it is there then please share the screenshot of your simulink model on info4eee@gmail.com to get more clarity about your problem.
Hello Chomnan Saedan, I think you are using the new version of MATLAB. In new version of MATLAB two additional commands are required to extract simulation data. PS : There are updates in "to workspace block" in latest version of MATLAB. For example: If you are using two "to workspace block" with variable "time" and "amplitude" then it will be stored in single "out" variable. You need to perform additional step to extract it by following command : "time = (out.time)" and "amplitude = (out.amplitude)"
@@info4eee Hi, in my case i cannot see the 'out' as well. its like none is transferred from the simulink. In my design i have two simulink models and one simulink model works well where it transferrers a definite value which is 51*1 dataset. But in the second simulink model i tries to transfer mean value of a constant signal. that variable cannot be seen in workspace. please help
Hello @@dilshangunatillake5336, If one Simulink model is transferring data then another Simulink model should also transfer data. In my opinion, there should sampling time mismatching.
@@LuqmanKhan-kv6xs, You can send the any variable {speed (w)} to the workspace with "to workspace block" from each four simulation model. Let four speed variable are w_1, w_2, w_3, and w_4. Along with that you can also send the simulation time to workspace with clock block. Now You can plot all four variable with respect to time using plot command (ua-cam.com/video/JTSWxm3Y3fk/v-deo.html).
There may be mismatching of sampling time with different blocks. If still problem remains then you can share screen shot of the problem through email on "info4eee@gmail.com". We will try to resolve your query.
Hello Mr. Viktor W, please follow the steps given below to save the simulation results with different input parameters in MATLAB Simulink. Suppose we want the simulation results of variable O at 100, 200, 300, and 400 amplitude as discussed in this video. 1. Set the amplitude of sine wave block *100* . Run the simulation and transfer the data of O in to variable *O1* by using command *"O1=O;"* on command window. 2. Set the amplitude of sine wave block *200* . Run the simulation and transfer the data of O in to variable *O2* by using command *"O2=O;"* on command window. 3. Set the amplitude of sine wave block *300* . Run the simulation and transfer the data of O in to variable *O3* by using command *"O3=O;"* on command window. 4. Set the amplitude of sine wave block *400* . Run the simulation and transfer the data of O in to variable *O4* by using command *"O2=O;"* on command window. 5. On command window, use the command *"hold"* to held the current plot. 6. On command window, use the command "plot(t,O1);" to plot first simulation result. 7. On command window, use the command "plot(t,O2);" to plot second simulation result. 8. On command window, use the command "plot(t,O3);" to plot third simulation result. 9. On command window, use the command "plot(t,O4);" to plot fourth simulation result. In this way, you can save the simulation results with different input parameters in MATLAB Simulink. You can also insert the legend to differentiate different results.
Suppose you want to measure the THD in Voltage waveform then just go through following steps. 1) Open respective scope block -> Configuration Properties -> Logging -> Check-in Log data to workspace -> Save format as dataset. 2) Open powergui block -> Tools -> FFT Analysis -> Check available signals and select appropriate signal. 3) After selecting number of cycles and fundamental frequency, click on display the frequency of respective signal i.e. Voltage.

My outputs are "Out.simout" for example instead of just "simout"? is there a fix?
Yes Ash B, "Out.simout" in not a valid variable in name in MATLAB. You can use "Out_simout" instead.
@@info4eee is that another variable in simulink?
@@FALLEN1ASH You can assign any name as per your need in simout block.

What is the use of solverblock
Which solver block you are talking about.
Please help, my simulation timing is 2 but when I am using simout transferring data timing becomes 4 means always double why?
There is option of decimation in to workspace block, Set this parameter as 1.
