Cross-Coupled Control Based on PID-Global Sliding Mode Control for Dual-Driven Servo Systems

In this paper, to improve the dynamics performance and synchronous motion accuracy for dual-driven servo systems, a control method that integrates cross-coupled control (CCC) and proportional-integral-derivative (PID) based on global sliding mode control (GSMC) is presented. On the one hand, in the actual applications, the cross-coupled control has shown the superiority in synchronous motion control due to structure characteristics. On the other, PID-GSMC can combine the advantages of PID and GSMC to further enhance the dynamics performance against external disturbances and uncertain parameters variations for dual-driven servo systems. The dynamics performance and effectiveness of the proposed control method will be investigated through simulations.
