But when I do that the pump stops working.

In this paper, an effort is made to control the speed of the DC motor and figure out the design process of a PID temperature controlling system of the electromagnetic. LabVIEW provides the flexibility of integration of data acquisition software/hardware with the process control application software for automated test and measurement applications. That's where I suppose to attach the 'error'. LabVIEW is a graphical programming language. I didn't use the entrance that called Process Variable in the PID VI. 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. Labview Based Pid Controller For Cylindrical Tank Level Controlling,IJSR - International Journal of Scientific Research(IJSR), IJSR is a double reviewed. The user chooses the set point - the height he wants. While the tank is being filled, the pumping suppose to get wicker until it stops.

LabVIEW stands for Laboratory Virtual Instrument Engineering Workbench, which is a software development environment for creating custom applications that are able to monitor and control the real-time data in engineering and science field applications. 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. 45+ LabVIEW Projects for Engineering Students. 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. PID compares the actual position of the DC motor with the desired position. The output is sent back to the PID controller in Uno microcontroller. DC motor will move by the user in LabVIEW for position control. I'm working on a project - level control in a tank with water. LabVIEW(GUI) sends serial command to the microcontroller for driving PWM pins of the DC motor.
