| 摘 要： | 针对半全局极值搜索算法的准确性和快速性之间存在相互制约的问题,提出了采用高通滤波器过滤反馈信号中的低频信号。用平均化方法证明了系统保持了半全局收敛性,放宽了对反馈增益要求较小参数的限制,还兼顾了系统的准确性和快速性。通过仿真对比发现基于高通滤波器的半全局极值搜索算法保持了系统半全局收敛性,提高了系统准确性和快速性。

| Abstract: | For issues of mutual constraints between the accuracy and rapidity of semi-global extremum seeking algorithm,the paper proposes the semi-global extremum seeking algorithm based on high-pass filter to relax the requirement of the small parameter of limit feedback gain.We use averaging method to prove that proposed algorithm maintains the system semi-global convergence and improves the system's accuracy and rapidity. Simulation shows that semi-global extremum seeking algorithm based on high-pass filter improves the semi-global convergence,accuracy and rapidity of the system. |
