Abstract: | The design and implementation of a pole placement adaptive controller are discussed for force control of the end milling process. The end milling process considered is a non-minimum phase system whose computational delay exceeds one half of the control interval. The internal model principle is included in the controller design to ensure a zero steady-state tracking error. Experimental results show that the pole placement adaptive controller is effective for force control of the non-minimum phase end milling operation and the closed-loop control system is stable over a wide range of cutting conditions. |
