HD-808/900 series expert self-tuning PID controllerFunctional Features
By combining fuzzy control theory with traditional PID control, the control process has the advantages of fast response, small overshoot, and high steady-state accuracy. It has a significant control effect on large pure lag objects that are difficult to control with conventional PID
HD-900 adds 30 program control functions on the basis of HD-808
