DC Motor speed control using PID Tune Simulation

[A.Hakim]

I'm interested to control a DC motor model but with another input which is TL.... for example in Labview there is simEx DC Motor.vi which has two inputs Voltage and TL if I set TL to Zero and concerned only with Voltage ...I can tune PID using the manual (trial and error) method (stated in this tutorial http://www.ni.com/white-paper/6931/en#toc1 ) but when I increase TL to some value, I can not tune PI controller...any help or suggestion please?

We might need some more information on what you are using and trying to do. I can't find the example you mentioned, what version of LabVIEW are you using?

Is the TL input you mentioned referring to Tyreus-Luyben rules for PID or something else? A screenshot of your code or some more details would be very helpful.

Thanks!

Hello,

I want to control the speed of the DC motor (In hardware) using IMC (Internal Model Control) tuned PID in labview. I have to interface the hardware with software using DAQ Card or using Arduino UNO R3.

At present I have to simulate the dc motor speed control in labview. Please suggest me how should I do the simulation.

Herewith attached the block diagram of my project.

Thanks & Regards,

Hello Neelam,

Thre is a very well documented white paper online you can refer to for  DC motor control using LabVIEW.

Best of luck with your project.

Hello Luis,

Thank you so much for the reference dear. I tried to simulate the same in Labview but I am getting this error" Error -2369 occurred at Transfer Function in PID+DC (NW).vi/Control & Simulation Loop" 

Please suggest me how to remove this error.

Thanks & Regards,
