This fuzzy controller can implement real - time regulation of the motor ' s rotational speed in light of the position error and its variable rate, therefore, the system can run in the direction of cutting down the position error with maximum speed when the system is under the condition of a higher position error. when the error is slight, the fuzzy controller also can reduce the motor ' s rotational speed gradually, thus the precision of the system will play a dominant role, which can create good conditions for an accurate stop when the position error diminished
模糊控制器可以根據位置誤差的大小以及位置誤差變化率的大小，實時的調節電動機的轉速，使系統在大的位置偏差的情況下能夠以最快的速度向著減小位置誤差的方向運行，在小誤差的情況下，能夠使電機的運行速度逐漸減小，使系統控制的精確性佔主導地位，為位置誤差等於零的時候能夠做到準確迅速的停車創造條件。
