The design and implementation of the high performance permanent magnet synchronous motor servo system

According to the high precision requirements of satellite antenna servo system,the paper designs a vector-contrdling permanent magnet synchronous motor(PMSM) servo system based on DSP.The whole digital system is applied to satellite antenna to realize the objective of adjusting the speed,determining the position and tracking it precisely.The novel control system based on TMS320f2812 and CPLD chip is proposed to satisfy the requirements of the high performance servo system.The hardware and software control procedures are designed and developed.The servo system achieves the field oriented vector control based on SVPWM,and has the motor parameter on-line estimation function and position and speed control function.The performance of the servo system is validated through the simulation and experimental results.The results indicate that the servo system has met the requirement of steady and dynamic performance index and realize the function requirement of the satellite antenna position control.Meanwhile it shows that the designed servo system could be implemented in other industrial control field and has certain practical values.
