Data-driven Control for Noncircular Turning Tool Servo System

摘要：

Based on the tracking and disturbance rejection requirements for noncircular turning process (NCTP), data-driven control method is applied in tool servo system. A model-free learning adaptive (MFLAC) composite control based noncircular turning process metering strategy with feedforward control and adaptive compensation is presented. In this scheme, a 3-tier composite control structure is adopted, feedforward control, a MFLAC feedback control and a non-linear Radial Basis Function (RBF) based compensator. This modularized controller design makes use of the periodicity of the NCTP effectively and improves the controller performance greatly.
