针对一个磁场中悬浮金属小球的控制问题，设计了有两输入一输出和九条规则的模糊控制器。控制器采用了一种新的模糊化和去模糊方法，它克服了通常的模糊化方法中由于把精确量分等级而带来的信息损失。模拟结果表明模糊控制与常规 Ｐ Ｉ Ｄ 方法相比，具有过渡时间短、超调量小和稳定性好的特点。用 Ｃ Ｍ Ｏ Ｓ电流型电路进行了设计，并用改进型 Ｃ Ｍ Ｏ Ｓ工艺流水，结果表明该电路较好地达到了设计要求。全部电路近 ３００ 个 Ｍ Ｏ Ｓ管，面积为 １１ ｍ ｍ ２， 功耗为１０７ ｍ Ｗ 。
Aiming at the control of suspended metal balls in a magnetic field, a fuzzy controller with two inputs and one output and nine rules is designed. The controller employs a new fuzzification and defuzzification method that overcomes the loss of information in the usual fuzzification method due to the level of precision. The simulation results show that the fuzzy control has the characteristics of short transient time, small overshoot and good stability compared with the conventional PID method. It is designed with C MO S current type circuit and improved C M O S process. The result shows that the circuit meets the design requirements well. Nearly 300 M O S tubes of all circuits, with an area of 11 m 2 and a power consumption of 107 mW.
