You'll also need to provide starting PID values, output limits, a setpoint, and a process variable. PV Noise Level - Estimate the noise level that will be included in the process variable.Keep in mind that faster response will result in higher overshoot which may not be desirable. Control Specification - This specifies how the systems will respond.This number will ideally be set so that the each oscillation period takes at least twenty control cycles. Relay Amplitude - Specifies the step change of the current setpoint up or down.
This will be more pronounced in slower systems. Your results will be more precise with more cycles but will require more time to execute. Relay Cycles - This tells the setpoint relay experiment how many cycles to use.Controller Type - Select what type of controller you are trying to tune.Once you have your system in a stable state, you will need to provide the VI with the autotuning parameters it will use to tune your system:
SolutionBefore you begin autotuning, you must establish a stable open-loop system, even if you cannot tune the system on your own.
