Hello FamilyGuy,
There are several considerations to keep in mind when choosing the design for your application. Things to keep in mind are: What development environment are you considering for your application? Will you be writing the program in LabVIEW? What driver are you using with your hardware device? What are the signal ranges and types you will be using?
That being said, I think there are several examples you could check out for your application. You can find the NI Example Finder in LabVIEW by going to the
Help menu and selecting
Find Examples. Specifically, I think you may be able to start your development with PID Control-Single Channel.vi. You can find this example by searching for "PID Control" or by navigating to
Hardware Input and Output>>DAQmx>>Control>>General. This example uses the NI-DAQmx driver in LabVIEW to demonstrate how to do a control loop using Analog Input and Analog Output. I am assuming that your thermistor input will be an analog signal. However, you would probably use a digital channel to switch the MOSFET device. If this is the case, you may need to modify the example slightly to output a digital signal. However, the example should still be a good place to start your programming efforts.
