Based on the basic principle of induction motor vector control system, design of speed sensor-less frequency control system is completed on the platform with the chip-TMS320F2812. For improving the coun-termeasures resistance and the dynamic performance, the method of speed model reference adaptive system is utilized. Also, a detailed description is given about how to design the hardware and software of the fre-quency control system. Lastly, experimental studies are carried out on the motor. The results show that the system can estimate the motor speed with precision and have a good dynamic control performance.
