摘要
对精密工作台的定位控制进行研究。提出一种参数自调整模糊控制的改进算法。该方法克服了常规模糊控制存在的静差和振荡问题。设计了模糊控制器的Simulink模型,仿真实验结果表明该方法相对于常规模糊控制具有良好的超调和响应快速性。通过优化自调整参数和模糊控制规则,可以得到更好的系统响应曲线。对于实际控制系统,该控制算法具有较好的稳定性。
In order to improve the positioning accuracy of the precision worktable, a modified parameter self-adjusting Fuzzy closedloop controller was design and simulated, which overcame the steady-state error and oscillation of the general fuzzy controller. Its Simulink model was established in MATLAB, and the response characteristic of the servo-worktable system was simulated and analyzed. Simulation results show that the parameter self-adjusting fuzzy control has the better overshoot and rapidity than the conven- tional fuzzy controller., especially to the actual system.
