考虑到矿井提升机的特点,实际运行中电机参数变化会使得常规PID控制方法的效果不太理想,因此将模糊控制思想和现代控制理论相结合,对交流调速系统的智能化控制进行了研究。选用带有自调整因子的模糊控制器替代原PI控制器,极大的改善了系统的动静态性能,使提升机系统满足快速、稳定和高精度的要求,同时又使系统的鲁棒性得到加强。 Taking into account the characteristics of mine hoist, the actual operation of the motor parameters will make the effect of conventional PID control less than ideal, so the fuzzy control theory and modern control theory, the intelligent control of AC speed regulation system were studied . Replacing the original PI controller with the fuzzy controller with self-adjusting factor greatly improves the static and dynamic performance of the system, and makes the hoist system meet the requirements of fast, stable and high precision, at the same time, the robustness of the system is obtained strengthen.
