摘　　要：为了有效抑制上肢力量训练器发生低频振荡,提高低频振荡收敛速度和计算效率,提出上肢力量训练器低频抑振参数协调优化方法。根据目标函数、经验小波变换法,建立上肢力量训练器低频振荡检测模型,得到检测信号并映射到特定范围内。采用经验小波变换的伸缩因子,获取检测信号频率特征,提取出低频抑振参数。利用线性微积分函数方程,构建低频抑振参数协调优化数学模型,并采用免疫遗传方法对其进行求解,完成低频抑振参数协调优化。实验结果表明,所提方法的低频抑振参数协调优化效果较好,能够有效抑制低频振荡,提高收敛速度和计算效率。In order to effectively restrain the low-frequency oscillation of upper limb strength training device and improve the convergence speed and calculation efficiency of low-frequency oscillation,a coordinated optimization method of low-frequency oscillation suppression parameters of upper limb strength training device is proposed.According to the objective function and empirical wavelet transform,the low frequency oscillation detection model of upper limb strength training device is established,and the detection signal is obtained and mapped to a specific range.The expansion factor of empirical wavelet transform is used to obtain the frequency characteristics of the detection signal and extract the low-frequency vibration suppression parameters.Based on the linear calculus function equation,the mathematical model of low-frequency vibration suppression parameters coordination optimization is established,and the immune genetic method is used to solve the model to complete the low-frequency vibration suppression parameters coordination optimization.The experimental results show that the proposed method can effectively suppress the low-frequency oscillation and improve the convergence speed and computational efficiency.
