说明: 采用Laser - PVDF 实验系统对纳米AlP/ SiO2 中激光超声信号进行采集. 利用小波的多尺度分解、重
构和消噪功能,提取出直达波及其反射回波,测量了时间间隔和纳米AlP/ SiO2 的纵波声速. 结果证明小波变换
的方法能有效地处理复杂激光超声信号.(Using Laser- PVDF experimental system of nano-AlP/SiO2 Laser ultrasonic signal acquisition. Using wavelet multiscale decomposition, reconstruction and de-noising function, extracted from direct wave and its reflection echo measured time interval and nano-AlP/SiO2 of the longitudinal wave speed of sound. wavelet transform results show that the method can effectively deal with the complexity of laser ultrasonic signals.)

说明: 20 世纪70 年代以来,人们从工业过程的特点出发,寻找对模型精度要求不高而同样能实现高质量控制性能的方法,预测控制就是在这种背景下发展起来的。预测控制技术最初由Richalet 和Cutler 提出[1 ] ,它最大程度地结合了工业实际的要求,综合效果好,已经在理论和应用方面取得了显著进展,各种预测控制算法不断地产生并得到发展。预测控制算法具有三大本质特征:预测模型、滚动优化和反馈校正[2 ] 。它是不断滚动的局部优化,而非全局最优。预测控制的特点:建模方便 采用非最小化描述的离散卷积和模型,信息冗余量大,有利于提高系统的鲁棒性 采用滚动优化策略,使模型失配、畸变、干扰等引起的不确定性及时得到弥补,从而得到较好的动态控制性能 可推广到有约束条件、大迟延、非最小相位以及非线性等过程,对模型精度要求不高,跟踪性能良好,更适应于复杂工业过程控制。
