I have a simulink file contain a PV model. but I couldn't simulate it as real time simulation on dspace 1103, I think because the model has a continuous elements such as exponential element. So, i can't simulate it.
who can help me to solve this problem? and is there a discrete model for...
[B]I tested my inverter experimentally and I obtained the THD of the inverter output voltage by using power analyzer YOKOGAWA WT1800 and it gave me a certain value. then i wanted to verify this value by the simulation results. where, i use a matlab simulink as a simulator. i used FFT tools of...
there is no one can help me for my demand!!!!!!.
i want to tell you i performed the simulink bolck of PI but the controll didn't work so i want to now the good way to make it where may be i'm doing something wrong.
thanks for all. and i'm still waiting your reply. i need it verey faster to...
Dear all;
How can i implement digital PI controller in simulink of matlab10? where i want to use it with DSPF2812.
i used the PI block but the system doesn't work properly.
any one can help me?
thanks alot.
I'm newer in using DSP in control system where i used it to implement my control for conversion system.
I used it with simulink and i perform my simulink blocks but i need to see the signals and variable inside the dsp during the operation of the ciruit hardware.
m question is that: 1- what is...
Hi everybody,
i have a question in dsp where i newer in using it . how can i make a synchronization between an analogue signal entered to dsp kit via internal ADC of the dsp and an internal signal generated inside the dsp. where those two signal i make another operation on them. where i...
hi every body,
now i'm working with DSP2812 and i added a source code file of my project and i added all header files to the project. also i added a .cmd file(F2812_EzDSP_RAM_lnk.cmd) and i added libraries file a .lib(rts2800_ml.lib) . where i'm using code composer 3.1.
and i made a compile to...
sorry, I am meaning by FPGA reset is that:
when i connect my power circuit (inverter) to the grid the FPGA disconnect and then no pulses will go to the switches of inverter. I don't know the reasons for this action.
I want someone to help me.
I want to know the reasons that cause the FPGA kit to reset. where I have inverter circuit and it was operating very good but now it work for a moment and then stopped and FPGA is reset. I can't understand what is happening.
please, any one know the reasons of this problem.
I tried to implement the PI controller code but i failed and i need it. so, if any one have a source code for this controller with vhdl please give me the code.
and i will be very thankful for him.
thanks very much for all
thanks berry for your reply because Ts/2 is very small so i canceled the term that contain this value. beacause i can't implement float value on FPGA. i tried to chang the values of kp and ki but it may should be less than 1 so, i don't know how can i implement it on FPGA also. if you have any...
please, I try to implement a PI digital controller in VHDL but my circuit does not work where PI code isn't correct. can anyone help me with a PI code by VHDL? Note, the equation that i use it in vhdl is : u(k)=u(k-1)+e(k)*(kp + ki*Ts/2) + e(k-1)* (ki*Ts/2 - kp) where: u : output signal o...
