摘　　要：为改善位置随动控制系统性能,运用现代控制理论中的状态反馈、极点配置、观测器等技术,同时对多个状态变量进行闭环控制。因存在不可直接量测的状态变量,进一步设计一个降维观测器,用估计值实现不可直接量测的状态变量反馈。设计与仿真在MATLAB环境下实现,得到了符合要求的结果。In order to improve capabilities of the position servocontrol system, use technologies like state feedback, pole assignment and observer, which belong to the present control theory, thus to make synchronously closed-loop control on several state variables. And due to indirect measurable state variable, make further design of a dimensionality reduction observer, and realize indirect measurable state variable feedback through estimated value. The design and simulation were achieved under MATLAB, and the result that could meet demands was obtained.
