摘要
位置伺服系统的外界干扰虽然各种各样,但是有的干扰是事先可以确知的.本文就是对这种事先能确知的外界干扰,应用预见控制的理论,给出了一种预见补偿算法.通过实际的数值仿真和实验的分析,表明只要选取合适的预见信息量,这种对已知外界干扰的预见补偿算法就可消除该干扰对系统的影响作用.从而说明了这种预见补偿算法的有效性和实际应用的可行性.
There are various external-disturbances on the position servo system,but some of these can bepreviewed. This paper presents a preview compensating algorithm for the foreknown external-disturbanceswith the help of the theory on preview control. The practical simulation of numerical value and the analysis ofexperiments show that this algorithm can get rid of the disturbances on the system only if selectingappropriate preview information. Therefore the algorithm is effective and feasible.
