Gain Scheduling Controller For Tool And Cutter Grinding Machine And Its Comparison With Fixed Gain Controller
This paper deals with closed loop control of CNC operated tool and cutter grinder machine with conventional
fixed gain controller and adaptive gain scheduling controller. Reliable spindle power model is developed for the purpose of
simulation and is validated. Fuzzy logic based gain scheduling control scheme for tool and cutter grinding machines is
proposed in this paper. Series of simulation work with different machine parameters and disturbance condition is carried out
to verify utility of the scheme. Performance of gain scheduling controller is compared with conventional fixed gain controller.
From simulation result it is clear that gain scheduling controller offers better tool protection against catastrophic failure and
also assures good productivity.
