Hi,
I’ve been trying to control a rather slow time constant system for temperature control and having a minimum integral gain of 0dB is somewhat frustrating. I can achieve the time response I desire by setting a low proportional gain, but then this limits the systems overall response range. For now I can manage by adjusting the offset manually through the api, but it would be nice if the PID controller offered a slow controller option like in the laser lock box.
Thanks!
Hello @JackAttack720 ,
Thank you for reaching out to Liquid Instruments! I will add this as a feature request. In the mean time, you can use the Laser Lock Box as a slow PID controller by setting the demodulation source to ‘None’ and configuring the fast controller to have 0 dB proportional gain, and all other parameters disabled. At this point, the fast controller just passes the signal to the slow PID and Output 2 is the output of the slow PID. I hope this can be a helpful workaround in the mean time!
