摘要


摘要:Bouc-Wen模型是基于非线性微分方程的一种迟滞模型,由于三角波等非光滑输入拐点处导数不存在,此模型无法适应此类非光滑输入信号。受信号预处理方法启发,基于不完全微分的柔化思想,文中对Bouc-Wen迟滞模型进行了改进,论述了其对音圈电机非光滑迟滞特性描述的合理性,给出了改进模型的离散形式。在三角波输入下,对原模型和改进模型传输特性进行了仿真比较。结果表明,改进Bouc-Wen模型克服了原模型不足,能有效描述迟滞特性,可实现性好,算法简洁,特别符合高速实时要求。



Abstract

Abstract: The Bouc-Wen model is one kind of hysteresis model based on the nonlinear differential equation. Because the derivatives at the inflexions of the triangular wave and other non-smooth inputs do not exist, this model is not suitable for those kinds of non-smooth inputs. Derived from the function of signal’s pre-processing, an improvement for the Bouc-Wen model was made, based on the soften idea of partial differential. The rationality of it for the voice coil motor was discussed, and the discrete form of the improved model was given. Under the triangular wave input, the input-output characteristic of the initial and improved model were compared. The simulation results indicate that the improved Bouc-Wen model could describe the hysteresis characteristic effectively, with good realizability, succinct algorithm compile. These advantages can specially meet the high speed and real-time requirements.
