pid control of 2nd order mass force system labview vi

But when I do that the pump stops working. That's where I suppose to attach the 'error'. This toolset includes PID Control, Fuzzy Logic Control, and Advanced Control VIs.

I didn't use the entrance that called Process Variable in the PID VI. The PID Control Toolset User Manual describes the new PID Control Toolset for LabVIEW. The DAQ measures the height - (height * 100) / wanted height -> gives us the error.īut, while the tank is being filled, and the error is getting smaller, the pumping strengh stays the same. Keywords: Wideband Control, Dynamic Vibration Absorber (ADVA), Multi-mode system, LabVIEW, State Machine Code. The user chooses the set point - the height he wants. A good controller forces the system to reach the set point quickly and remain. While the tank is being filled, the pumping suppose to get wicker until it stops. Figure 19: The PID sub-VI and related equations as they appear in LabVIEW. M - stands for the strengh of the water pumpingĮ - stands for the error - difference between the height I want, and the height found in the tank.Īs bigger the difference between the wanted height and the found height, as stronger the strengh of the pumping. The user can choose how to control the water with the controllers - P, Pi, Pd or the combined PID.įor example, the P control works like the equation m=P*e I suppose to control the level of the water, for example - the user can choose the height he wants the water to fill the tank, and a pump starts to pour water into the tank. simulation LabVIEW/CDSim NI myRIO-1900 PID and MPC.
