摘要
针对伺服系统在低速情况下具有较强的摩擦现象,是一个强非线性系统,本文将模糊控制与PID控制手段结合起来,提出采用非对称模糊PID控制方法,将其引入伺服系统的位置环中,同时建立了基于MATLAB/SIMULINK的系统仿真图。通过仿真试验,验证了非对称模糊PID控制方法具有较好的控制精度和稳定性,该控制方法可使系统的性能有所提高。
Aimed at nolinear characteristic of a position servo system with serious friction under low speed, an asymmetric fuzzy PID controller (SAFC) is introduced in this paper, which combined fuzzy control method with PID control method. After a lot of theoretic studies,the asymmetric fuzzy PID controller is used as the position controller of a two - quality position servo system. At the same time the system simulation model is built with MATLAB/SIMULINK. The simulation results verify that the controller not only improves dynamic and static response of servo system,but also strong robustness is obtained.
