摘　　要：实现三维模糊控制效果,而控制规则数与二维模糊控制器相当。模糊控制规则解析生成。模糊推理方法基于相平面,计算量小,直接用输入连续量进行推理。该控制器结构及算法简单,易于在线实现,具有通用性。将其用于交流调速系统,实验结果表明控制性能较PI算法更佳。A three-term fuzzy controller was implemented by simply using two-term fuzzy control rules. The fuzzy control rules were generated analytically. The method of fuzzy inference based on phase plane had less computational burden, while the fuzzy inputs could be continuous, which improved the precision. This controller had simpler structure and control algorithms and could be realized on line analytically. The experiment shows that when it is used in AC speed control system, its performance is better than that of PI controller, and the system is much more robust.
