一种改进的模糊PD控制器

充分利用非线性跟踪微分器获得高质量微分信号的特性,将跟踪微分器与传统的简单模糊PD控制器相结合,提出一种简单的高性能的改进的模糊PD控制器.该改进模糊控制器的最显著特点是对测量噪声的强鲁棒性和工程易实现性.数值仿真证明了其有效性和高效性.

Make full use of the characteristics of nonlinear tracking differentiator (TD) to provide high quality differential signal of the non-continuous measured signal with noise, a simple enhanced fuzzy PD controller is developed by combining the TD with a conventional fuzzy PD controller. The main improvement of the proposed simple enhanced fuzzy PD controller is that it has high robustness against the noise and is easy for engineering implementation. Simulation results show the effectiveness and efficiency of the proposed controller.
