โœฆ Synopsis


In this paper, we propose a direct pole placement adaptive tracking scheme for non-minimum-phase, open-loop stable, linear plants with time delays. This controller utilizes the internal model principle to eliminate steady-state tracking error for signals with known distinct frequencies. The controller order depends only on the number of frequencies in the reference input, but not on the order of the plant. It is shown that with su ciently small loop gain, the controller can guarantee stable closed loop, and asymptotic tracking.

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 inclu
