Strong Tracking Filter in the Application of Variable Frequency Speed Regulation in Microcomputer Water Supply System

设计了一种基于强跟踪滤波器的变频调速微机给水系统,通过强跟踪滤波器可以对控制系统的输入叠加噪声、未建模动态及参数噪声进行滤波处理,并对控制系统的随机误差进行补偿,从而有效地提高了系统的可靠性、稳定性和控制精度.仿真结果表明,强跟踪滤波器能有效地估计变频调速微机给水系统的状态,降低噪声对控制系统的影响,提高控制系统的鲁棒性.

A microcomputer water supply system of variable frequency speed regulation based on strong tracking filter is designed. Superimposed noise of the control system, unmodeled dynamics and parameter noise can be performed filter process by strong tracking filter, and random error of the control system can also be compensated. So the reliability, stability and control accuracy of the system have been improved effectively. The simulation results show that strong tracking filter can effectively estimate the state of the system,reduce the noise influence on the control system and improve its robustness.
