| 摘 要： | 首先离线设计出具有特定低通特性的滤波器作为闭环系统参考模型，然后利用Ｄａｕｂｅｃｈｉｅｓ分解／综合滤波器，在线分频段估计系统的传递函数，最后利用最小二乘法优化频域目标函数而得到ＰＩＤ控制器的三个参数，仿真结果验证了本算法的有效性。

| Abstract: | At first, this paper designs filter which has specific band pass characteristics to serve as reference model of closed loop off line, and then takes advantage of Daubechies analysis/synthesis filter bank to estimate system transfer function by means of band wise approximation on line. Finaly, gets the three parameters of PID controller by way of optimization of target function in frequency domain. The simulation results show the effectiveness of this algorithm. |
