Abstract:According to the needs of the assessment of AC servo system control performance,after a comprehensive comparison of the characteristics of performance evaluation indicators such as ISE,IAE,ITAE,etc.a IITAE(improved indicators ITAE)as a servo system control performance assessment method was designed,which was used to design the servo control parameter self-tuning model based on the Coordinate rotation algorithm and a real-time simulation was conducted.The results show that:The IITAE performance evaluation index has good applicability and coordinate rotation algorithm is an efficient way to get optimal control parameters of the servo system.
