摘要
为提高永磁同步电机调速系统的控制性能,文中针对传统PID控制器响应时间长,且易出现震荡、稳定性差的缺点,设计了变论域自适应模糊PID控制器。该控制器采用Fuzzy1和Fuzzy2两部分组成,分别负责粗调和细调,以确保系统控制的快速性、精确性以及稳定性。通过Matlab仿真证明了改进的PID控制器显著提高了系统的抗干扰能力,并且响应快、稳定性好、具有较强的鲁棒性。
In order to improve the control performance of permanent magnet synchronous motor drive system,a variable universe adaptive fuzzy PID controller is designed for the traditional PID controller with long response time and easy to shock and unstable. The controller uses the Fuzzy1 and Fuzzy2 is composed of two parts,which are responsible for coarse and fine adjustment,to ensure that the system is fast,control accuracy and stability. Finally,the Matlab simulation proves that the improved PID controller obviously improves the anti-interference ability of the system,and has fast response,good stability and strong robustness.
