Filename: pid_velocity_control.vi
Requirements: View

This virtual instrument (VI) demonstrates how to use the "PID.vi" to implement a closed loop control strategy to control the velocity of a DC motor. The feedback signal which is the velocity of the DC motor is compared to your Setpoint and the difference between the two is used by the PID Algorithm to make a decision on what the output should be. PID parameters can be determined either by using analytical methods (Step or Frequency Response) or using trial-and error method. Please follow the instruction on the Front Panel of this VI.

This is a software timed control system where the Loop Delay controls the rate of acquisition and generation.
