Lab 13 Basic concepts of LabVIEW programming and root locus techniques ECE 3709L-07 May 13 th , 2023 Objectives
The objective of this lab is to learn basic concepts of LabVIEW programming. Pre-Lab Students are to download LabVIEW. Students are required to read information about LabVIEW available on NI website and/or from other credible sources to get familiarized with the software. Lab Section B1. Understanding LabVIEW virtual instrument (VI)
Figure 1 Simulation 1. I confirmed that the PID controller functioned within a closed loop to accurately follow the desired setpoint. This was done by ensuring that the controller consistently adjusted the control signal according to the sensor's feedback. Additionally, I monitored both the input and output signals of the controller to verify its operation. In our scenario, the input signal represented the setpoint value, set at 50, while the output signal indicated the controller signal transmitted to the actuator. Figure 2 Tank Level w/ Disturbance 2. From my observations, I noticed that activating valve HV 102 has resulted in an increase in the controller output. This can be observed in Figure 2, where a slight overfilling of the tank is indicated. Although the setpoint was initially set to 50, the figure shows a value of 50.20. While the controller continues to perform well overall, this overflow can be
