在输入电流信号的不同幅度和偏置电平下，描述了音圈电机的磁滞非线性特性。测量数据表明，输出-输入磁滞回线的非对称特性强烈依赖于输入信号的幅度和偏置。提出了一种改进的Prandtl-Ishlinskii模型来模拟音圈电机的与速率无关的磁滞非线性。该迟滞模型由一系列广义算子和一个基于费米-狄拉克分布的输入函数组成。在不同幅值的输入电流信号下的模型响应与实测数据的比较表明，所提出的模型能够有效地描述音圈电机在4.3 mm行程范围内的与速率无关的非线性迟滞特性。随后，所提出的Prandtl-Ishlinskii模型的逆得到解析。利用逆模型作为前馈补偿器，在不使用反馈控制技术的情况下补偿与速率无关的迟滞非线性。补偿实验验证了逆模型的有效性。
The hysteresis nonlinearities of a voice coil motor are characterized under different amplitudes and bias levels of input current signals. The measured data reveal that the asymmetric characteristics of the output-input hysteresis loop are strongly dependent on the amplitude and bias of the input signal. A modified Prandtl-Ishlinskii model is proposed in this study to model the rate-independent hysteresis nonlinearities of a voice coil motor. The proposed hysteresis model is composed of a series of generalized operators and an input function based on Fermi-Dirac distribution. Comparisons of the model responses with the measured data under different amplitudes of input current signals indicate that the proposed model can effectively describe the rate-independent nonlinear hysteresis properties of the voice coil motor within the travel range of 4.3 mm. Subsequently, the inverse of the proposed Prandtl-Ishlinskii model is obtained analytically. The inverse model is utilized as a feedforward compensator to compensate the rate-independent hysteresis nonlinearities without using feedback control techniques. The compensation experiments are performed to verify the validity of the inverse model.
