H_∞ Speed Control for Permanent Magnet Ring Torque Motor Based on Multi-objective Genetic Algorithms

Sun Yibiao Zhao Yan Wang Chengyuan (Electric Engineering Institute of Shenyang University of Technology, Shenyang 110178)  
During to adopt direct drive technology, permanent-magnet ring torque motor rotary feeding System used in NC rotary table is more sensitive to load disturbances and parameters variations, which greatly reduces servo performances of the system. An H∞ speed controller was designed by multi-objective genetic algorithms to optimize the parameters of H∞ speed control. Compared with conventional H∞ speed control, this control method effectively rejects the effect of load disturbances and parameters variations on NC rotary table servo system to enable the system to have better robustness, achieves good tracking response. Simulation results show that the proposed multi-objective genetic algorithms H∞ speed control enables the NC rotary table rotary feeding system to be better in robustness and rapidity against load disturbances and parameters variations.
