无速度传感器是电机调速的一个新发展方向,它具有免维护、不受电机和传感器参数影响等优点。矢量控制技术已经发展到实用化阶段,在目前的矢量控制技术中,速度调节器和转矩调节器都采用常规的PI控制器。在工程应用中,整定PI参数较为困难。将遗传优化算法引入矢量控制的速度调节器的参数寻优中,采用自适应遗传算法整定PI参数,仿真结果表明,经遗传优化后的系统具有很好的静、动态性能和鲁棒性。
Sensorless speed sensor is a new direction of motor speed control, it has maintenance-free, free from motor and sensor parameters and other advantages. Vector control technology has been developed to practical stage, in the current vector control technology, speed regulator and torque regulator are used conventional PI controller. In engineering applications, tuning PI parameters is more difficult. The genetic algorithm is introduced into the parameter optimization of the vector control speed regulator. The adaptive genetic algorithm is used to set the PI parameters. The simulation results show that the system has good static and dynamic performance and robustness.
