【摘要】 控制系统的性能是超声电火花复合加工性能好坏的关键,对于控制系统而言,超声电火花复合加工是一个典型的高度非线性、强耦合的时变复杂系统。针对这一特点,设计了新型模糊神经网络控制器,给出了学习算法。该控制器可自动学习模糊控制规则,并随系统的变化自动调节模糊控制规则,通过普通电火花加工设备提取出加工效果试验数据,建立加工效果与放电参数之间的关系模型,对放电间隙进行实时控制。更多还原

【Abstract】 Ultrasonic vibration assisted electric discharge machining(USEDM) is the 3C(complex plant/complex task/complex environment) system.The performance of control system is crucial for compound system.A new FNN controller is developed and the learning algorithm is designed in this paper.The controller can learn self and adjust the controlling rules with the condition changing.Make use of experiment data to set up the model,which controls the pulse interval.更多还原
