| 摘 要： | 针对一类参数未知、高阶有滞后的定常系统的控制问题,提出了在特征建模基础上,用有滞后的二阶时变差分方程来代替实际的对象特性,并给出了分析证明.稳态时,该特征模型与高阶滞后对象的输出保持一致,在动态过程中,动态输出误差保持在一定范围内,从而可以进一步按照特征模型设计控制器.从仿真结果可以看出,系统跟踪误差能保持在一定的范围内,表明了这种基于特征模型的控制方法的有效性和实用性.

| Abstract: | This paper presents a method to replace the practical plant characteristics using 2-order time varying difference equation with time delay for a kind of parameters unknown and high order,as well as time delay constant system.The analysis and proof are also given.In steady state,the characteristic model is equivalent to its practical plant in output,and the output error can remain within a permitted error limit in dynamic process,so the controller can be designed according to characteristic model.From the simulation result,tracking error can remain within a permitted error limit.It proves that the method based on characteristic model is valid and applicable. |
