| Abstract: | For controlling time-varying and non-minimum phase machining processes effectively, the pole placement design approach of adaptive controller has been studied. An efficient self-tuning control algorithm has been proposed for the control of non-minimum phase machining processes. Its effectiveness has been verified by the control experiments of milling processes with varying cutting depth and non-minimum phase. Some comments regarding the selection of appropriate observer parameters and desired poles have been given for designing a good-performance adaptive controller. |
