![]() The 10kohm value seems to be rather flexible with the LabVIEW Arduino library, and I cannot really understand why. My plan is to use the step response for the plant to set the controller or make a relay based controller from scratch from my previous knowledge of the problem.Ī few days back I finally got my 10k thermistors from eBay. My experience with the library is that this results in a poorly tuned controller. ![]() The autotuner function in the LabVIEW PID library seems to be more sensitive to having a working PID controller before trying to excite the plant with on/off signals. I have previously used relay autotuners successfully to set PID controllers with microcontrollers. I tested the PID relay autotuner, which is a tuner that uses on/off signals to test the plant response. My first test was to use a potmeter as an input for a PID controller setpoint and use a simulated plant to test the PID functionality. I have been testing the LabVIEW PID library in combination with the Arduino library while waiting for my thermistors to arrive. LabVIEW has library for both fuzzy and PID controllers. In my previous post I wrote that I wanted to use LabVIEW in combination with an additional Arduino library and the Arduino device to work as a controller.
