具有模型动态补偿的内模控制

Internal Model Control with a Dynamic Model Compensator

本文提出了一种模型动态补偿方法,以减小模型与对象之间的失配,改善内模控制器对付时变系统的能力。该模型动态补偿器依据波波夫超稳定理论进行设计,保证了模型补偿结构的稳定性。仿真实验证明,该方法有较强的鲁棒性,能对付在一定范围内变化的时变系统,改进了内模控制器的性能。

In this paper, a dynamic model compensator is proposed to decrease the mismatch be- tween the model and the process, so as to improve the performance of the internal model con- troller when a time-varying process in handled. As the dynamic model compensator is de- signed based on the hyperstability theory proposed by V.M.Popov, the stability of the struc- ture of the model compensation is guaranteed. The experiments of simulation show that the approach proposed by the paper is rather robust and can deal with the system where the pa- rameters may vary within a certain extent. The comparision demonstrates that the perfor- mance of the internal model controller is improved.
