摘要:
该文对线性离散系统的最优预见控制方法进行了研究。这种方法在二次型性能指标中综合考虑跟踪误差和控制量的变化 ,在设计反馈控制器的基础上 ,利用已知的未来目标值及未来干扰信号设计前馈补偿器 ,进一步改善了系统的性能。该文讨论了最优预见控制设计方法的关键技术 ,即预见步数的选取问题 ,推导了预见步数与性能指标函数值之间的关系 ,并给出了预见步数的选取方法。
Abstract:
The opt imal preview cont rol method of the linear discrete system is studied. In the method of opt imal preview cont rol, tracking errors and control increments are both considered in the quadratic cost funct ion. Integ rat ing the general optimal servo system w ith a preview feed-forw ard compensator that feeds forw ard future demands and future disturbing signals produces an opt imal preview servo system. This integration w ill enhance the performance of the servo system. The key technique of choosing preview steps designing opt imal preview control is discussed. The relat ionship betw een cost function value and preview steps is studied and methods of choosing preview steps are proposed.
