摘　　要：在二阶系统测速反馈控制的变阻尼技术中,传统的线性变阻尼和平方型变阻尼关系式动态性能存在一定的优化空间。在研究变阻尼传统数学表达式的基础上,引入新参数,提出一种二次分段的n次方型变阻尼关系式。经仿真验证,在参数相同的情况下,二次分段的n次方型变阻尼关系式改善了系统动态性能。In the variable damping technology of speed measurement feedback control for second-order systems,there is a certain optimization space for the dynamic performance of the traditional linear variable damping and square variable damping relations.Based on the study of the traditional mathematical expression of variable damping,a quadratic piecewise n-th power variable damping relationship is proposed by introducing new parameters.The simulation results show that the quadratic piecewise n-th power variable damping relationship improves the dynamic performance of the system under the same parameters.
