当三轴转台低速运行时，摩擦力矩对控制性能影响较大，导致跟踪效果较差。提出了一种基于模糊推理的变论域模糊控制方法。设计了转台变论域模糊控制器。它用模糊推理代替函数模型设计比例因子，根据输入输出值改变模糊控制器的输入输出论域。通过对PID、模糊PID和变论域模糊三种不同控制策略下转台系统低速性能特性的仿真比较，验证了变论域模糊控制能有效提高控制系统性能，具有较强的适应性。
When the three-axis turntable runs at a low speed condition, the friction torque has great influence on the control performance and leads to bad tracking results. The paper puts forward the variable universe fuzzy control method based on fuzzy inference. The turntable variable universe fuzzy controller has been de-signed. It uses fuzzy inference to substitute function model design scaling factor which changes the universe of inputs and output of the fuzzy controller according to the inputs and output value. By comparing the low speed performance characteristics of the turntable system simulation under three different control strategies which are PID, Fuzzy PID and Variable Universe Fuzzy, it verifies the variable universe fuzzy control can effectively improve the control system performance, and has a strong adaptability.
