Research of thermal characteristics has been a key issue in the development of high-speed feed system. The thermal positioning error of a ball-screw is one of the most important objects to consider for high-accuracy and high-speed machine tools. The research work undertaken herein ultimately aims at the development of a comprehensive thermal error identification model with high accuracy and robust. Using multi-class least squares support vector machines (LS-SVM), the thermal positioning error of the feed system is identified with the variance and mean square value of the temperatures of supporting bearings and screw-nut as feature vector. A series of experiments were carried out on a self-made quasi high-speed feed system experimental bench HUST-FS-001 to verify the identification capacity of the presented method. The results show that the recommended model can be used to predict the thermal error of a feed system with good accuracy, which is better than the ordinary BP and RBF neural network. The work described in this paper lays a solid foundation of thermal error prediction and compensation in a feed system.

针对暖通空调HVAC系统中由于存在高度非线性、时变特征以及扰动和不确定性等因素而难以控制的特点,提出基于Takagi-Sugeno(T-S)模糊模型的预测函数控制器设计方法。该方法通过最小二乘辨识算法建立系统的模糊T-S模型,然后基于模糊全局线性化预测模型,采用预测函数控制算法设计系统控制律。仿真实验结果表明该算法是一种跟踪性能好、鲁棒性强的有效控制方法。与常规的PID控制器相比,该方法具有超调量小、调整时间短等优良的动态性能。

提出一种完全基于激励和结构响应实测数据的结构动力系统非线性恢复力识别方法,并通过在一个4层钢结构模型中引入具有非线性特性的磁流变阻尼器(MR)模拟非线性恢复力,基于此模型结构在不同的激励方式下的动力响应测量数据,验证了该方法的有效性。对于结构的各自由度均受到激励的情况,运用最小二乘拟合算法识别出等效线性系统的物理参数(质量、刚度和阻尼矩阵),进而得到模型结构振动过程中MR阻尼力随时间变化情况并与实验实测结果进行了比较。针对结构仅在有限自由度上受到激励的情况,对以上方法进行了改进,提出了一种非线性系统恢复力的非参数化识别方法,利用结构中弹性恢复力的对称关系,分步确定了结构各层间恢复力模型,从而得到MR恢复力的大小并与实测结果进行了比较。结果表明,基于时域实测信号的非线性系统恢复力识别法在完整激励和非完整激励下均能有效地识别结构的非线性恢复力特性。文章所述方法可以运用于工程结构在动力荷载作用下的损伤发生发展过程的监测与识别。
