| Abstract: | The autoregressive (AR) time series model is usually used as a forecasting model for compensatory control of roundness in machining processes. The shortcomings arising from using the AR model are discussed and the optimal control equations have been derived. It is suggested that the ARV model be used instead of AR from the point of view of minimum variance control. A self-tuning regulator is proposed to overcome the effect of slow time-varying characteristics of machining environments on the accuracy of forecasting control. |
