Abstract:In order to improve the control performance of the position servo system, a high-performance position servo two-degree-of-freedom control method is proposed. Based on the idea of two degree of freedom control, through the speed loop control analysis, the loop compensation control method of the speed loop is proposed. The feed forward compensation controller is designed to design a two-degree-of-freedom controller by modifying the speed loop regulator and position loop regulator of the position servo control system. The experimental verification based on the vector control strategy of rotor flux linkage is carried out. The experimental results show that the control method is feasible and effective, and has engineering practical value.
