Note, Auto Tune is not available for HF2 instruments.įor HF2 instruments there are two main cases to differentiate between,ĭefined by whether type is set to "pid" or "pll" (see This functionality continuously updates the instrument’s PID parameters specified by tuner/mode in order to minimize the residual error signal. The Auto Tune functionality may be additionally enabled by setting tune to 1 and configuring the parameters in the tuner branch. Transfer the optimized gain parameters from the Advisor Module to the instrument’s nodes by setting the todevice parameter to 1.Įnable the instrument’s PID ( /DEV…./PIDS/n/ENABLE). Read out the optimized parameters, Bode and step response plot data (see Figure 1) for inspection using get(). Optimization may take up to a minute to complete, but is much quicker in most cases. The optimization process has finished when the value of calculate Start optimization of the PID parameters by setting the calculate parameter to 1. See PID Advisor Module Node Tree for a full list of PID Advisor parameters. If values are specified for the P, I and D gains they serve as initial values for the optimization process. Create an instance of the PID Advisor module.Ĭonfigure the module’s parameters using set() to specify, for example, which of the instrument’s PIDs to use and which type of device under test (DUT) to model. ![]()
