A Research on Cross Coupled Contour Error Compensation Using Fuzzy Inference

A new cross coupled contour error compensator using fuzzy inference for multiaxial contouring system is presented here, and the work principle,algorithm and design procedure are described. Without any extra hardware and any changes in each axial position control loop, the new compensator provides each axis with an additional conpensating function according to the contour errors by fuzzs inference and selflearning and correcting method. Therefor the contour accuracy of the total system is modified. The results of digital simulations and experiments on a typical two axis contouring system indicate that the feasibility and effectiveness of this new compensating method are satisfactory.
