Variable-Gain Cross-Coupling Controller for Contouring

Summary The increasing trend for higher precision in manufacturing systems has brought an increasing interest in the design of servo controller. One of the most effective methodologies for contouring applications is the cross-coupling control (CCC). This paper introduces a new CCC method which utilizes variable gins that are adjusted in process according to the shape of the part. The variable-gain CCC enables a contour error reduction of 3:1 to 10:1, depending upon the starung point and the resolution of the system do well as the contour type. The paper presents analysis and stimulation results.
