Pid control step labview8/2/2023 ![]() ![]() In order to achieve the gain=12V/0.52V in the feedback loop, we need to set the resistance of the potentiometer This has precisely been implemented in the feedback loop amplifier. Therefore, the tachometer output voltage needs to be amplified with a gain ratio of 12V/0.52V to infer the actual input voltage to the DC motor. On the other hand, motor’s speed is measured through the tachometer which produces 0.52V signal for 1000 RPM shaft speed. The DC motor rotates at 1000 RPM when connected to a 12V input signal with no-load condition. The turntable is controlled by a DC motor with a tachometer. The circuit diagram of the above physical circuit is as below. You can see the setup of the experiment below. The interface between the digital controller and analog circuit is made through a data acquisition system (DAQ) from Texas Instruments. The objective of this experiment was to implementing an analog circuit to communicate a turntable and controlling its speed through a digitally implemented PID controller. We describe here the effectiveness of PID controller for a single-input-single-output (SISO) system using experiment. ![]()
