Smith补偿器的非线性校正及系统稳定鲁棒性

Asymmetrical Nonlinear Correct for Smith Compensator Controller and the Robustness of System Stability

利用非对称非线性的环节对Smith补偿器进行校正,并用于间接加热蒸煮过程控制,仿真表明闭环系统具有较好的关于模型不匹配的稳定鲁棒性。

The Smith compensator controller corrected by a varied dead zone's asymmetrical nonlinear method, is studied and used in the simulation of the process control of indirect steaming, the results shows that the system which controlled by a corrected Smith compensator controller has good robustness of stability while the process and it's modal is not matched.
