Abstract:
将增量谐波平衡法应用到非线性系统的建模和参数识别中,针对Mathieu-Duffing方程,推导了利用增量谐波平衡原理识别参数激励非线性系统参数的方法.该方法改进了增量谐波平衡方法的推导过程,通过数值模拟对比研究了谐波平衡非线性识别(harmonic balance nonlinearity identification,HBNID)和增量谐波平衡非线性识别(incremental harmonic balance nonlinearity identification,IHBNID)的效果,验证了增量谐波平衡非线性识别的有效性.结果表明,增量谐波平衡非线性识别的计算效率较高,计算精度和抗噪能...
