We are working with SMA Actuator and try to control it using PID Controller.
We are using DAQ System NI PXIE-6341. We are working with NI PID toolkit and are using PID Autotuning vi.Our plant open loop response time i.e. heating time of system is 11 sec and cooling time varies from 15-20 sec. We are presently acquiring 200 samples at sample rate 1k.The problem arises in optimizing time for closed loop system. What should be the sample rate of the system?
