FUZZY LOGIC CONTROL BASED ON GENETIC ALGORITHMS FOR MULTIPLE DEGREE OF FREEDOM NONLINEAR VIBRATION

由于非线性系统的复杂性，难以得到基于线性控制规律的有效控制方法。本文对于复杂的多自由度非线性振动系统提出了基于遗传算法的主动模糊控制方法。通过此方法，得到了控制多自由度非线性振动的模糊控制规则及其优化的各种参数。针对转子非线性振动系统的数值仿真表明了该振动主动控制方法的有效性。

Because of the complexity of nonlinear systems, it is difficult to obtain an effective control scheme based on linear control law. In this paper, a fuzzy logic control based on genetic algorithms for complex nonlinear vibration systems of multiple degree of freedom is proposed. The rule of fuzzy control and parameters optimized for nonlinear vibration control are obtained. The numerical simulation of a nonlinear rotor system shows the effectiveness of this control method.
