Abstract:
      In order to control the pulp level in flotation column which has long time - delay character and great inertia, and is difficult to establish exact mathematical model, a Fuzzy - PID dual mode control with Fuzzy logic and PID is applied. This method has both the agility and fast response of fuzzy logic control and high precision of PID control. With the very stable and reliable instruments, this method has a good effect and realizes the stable control of flotation column.
