摘　　要：极点配置是控制理论课程中的重要内容,鲁棒性是衡量线性定常控制系统稳定性能的重要指标。文中提出了一种解决具有不确定性参数线性系统的鲁棒极点配置问题的方法,其中系统鲁棒性的指标采用加权的特征系数灵敏度,目标函数的求解采用标准的具有二次收敛性质的参数最优化方法。设计实例证实了该方法的可行性,故可作为控制理论课程的实际教学。Pole placement is an important content in the classical control theory course, and robustness is an important indicator to measure the stability of linear time-invariant control systems. This paper proposes a method to solve the problem of robust pole placement for linear systems with uncertain parameters. The system robustness index uses weighted characteristic coefficient sensitivity, and the objective function is solved using standard quadratic convergence parameters optimal method. An example is designed to prove the feasibility of the method, which can be used as the actual teaching of the classical control theory course..
