| 摘 要： | 研究了预见跟踪控制问题，即控制器可利用过去、现在和未来的信息来决定所施加控制量的大小．通常的作法是通过把未来预见信息加入控制量中来实现的．提出了一种不同的作法：利用未来目标值及系统的当前状态产生一个虚拟目标值，让系统转而去跟踪这个已被事先处理过的目标值信号，从而提高了系统的控制精度同时减少了控制所需的能量．数值仿真表明了这种方法的优越性．

| Abstract: | This paper deals with the preview tracking problem, in which a controller can use future information as well as present and past information in deciding the control. Usually, the preview of future desired output is added to control vector to improve tracking performance. A different control scheme, which creat an imaginary input signal by using future and present information, is proposed. When tracking this signal, the system can obtain better performance and use less control energy than general optimal preview servo system. A simulation of air slide linear motor control is presented to show its advantage to optimal servo system and optimal preview servo system. |
