【摘要】 为了能够在同伦法根轨迹校正设计中减少同伦不动点的个数,研究了同伦不动点个数与相应的约束条件,提出了条件极点配置的方法,减少了闭环零点的个数,降低了闭环零点对于系统动态性能的影响。在动态性能等价的基础上,可以实现在约束条件下同伦不动点的各种情况。本文所论述的方法是同伦法根轨迹校正设计方法的补充与扩展,完善了在经典控制理论的框架下实现闭环极点配置的方法。更多还原

【Abstract】 For lessening the number of homotopic fixed point in root locus system compensation by means of the homotopic method,it is investigated that the number of homotopic fixed point and their restrict conditions,brought up a method of the constrained pole disposition that can reduse the number of closed loop zeros and decrease its influence in dynamic performance.it can be realized that a couple of instance under resitrict conditions in a means of the eqivlence of dynamic performance.The method in this article is a supplement and extending for that of root locus system compensation by means of the homotopic method,as well as perfecting the closed loop pole disposition in the dimain of classic control theory.更多还原
