| 中文摘要:基于校正环节设计过程复杂、设计效率低下，采用标准二阶响应曲线与上升时间、调整时间、超调时间、峰值时间具有一一对应的关系，根据时域指标快速确定响应函数。S域中，响应函数H(S)、校正环节Gd(S)和被控对像的闭环传递函数Go(S)三者有H(S)=Gd(S)*Go(S)的关系，在已知H(S)和Go(S)函数下可通过函数运算得到Gd(S)表达式。通过MATLAB仿真，验证指标法设计方法正确、可靠。利用此方法在高精度转台控制中运用，控制误差在±0.002°以内，满足设计要求。 |

| Abstract:Based on the correction of the design process complex，low design efficiency，the standard second order response is used and rise time，adjust time，over time，time to peak with one to one relationship，according to the time domain index to quickly determine the response function，the s domain response function H (s)，correction link Gd (s) and H (s) = Gd (s) *Go (s) accused of like the closed loop transfer function G0 (s) three，Gd (s) expression is obtained through the calculation of a function in the function (s) known H (s) and go.By MATLAB simulation,the design method of the index method is correct and reliable,the control error is less than 0.002 degree，which satisfies the design requirement in the high precision turntable control. |
