Design of Distributed Cross-Coupled Controller Based on Motion Control Bus
Improvement of contour precision is one of the important issues in counter-following applications. Currently cross-coupled control method is widely adopted in industrial motion controller, which can significantly reduce contouring error composed by multiaxis. Conventional cross-coupled controller, however, is a centralized one which must be implemented as a whole in computer numerical controller (CNC). Thus it results in many disadvantages such as augment of computing task, degradation of control performance, and so on. This paper analyzes the numerical control system structure, cross-coupled control characteristics and fieldbus technology, proposes a design method of distributed cross-coupled controller (DCCC) based on motion control bus (MCB). The advantages of the DCCC is analyzed in theory, and verified through experiments. Making full use of currently advanced numerical motion control bus and servo in motion control, this method is consistent with the technology development of motion control system.
