一类非自衡对象的两自由度内模控制

Two-degree-of Freedom Internal Model Control for Integrating Process

针对常规一自由度内模控制在非自衡对象中应用的不足,提出了一种基于互质分解的两自由度内模控制器设计方法,并采用H2优化改善了系统的动态性能.一类非自衡二阶非最小相位过程的仿真结果表明,这种方法可使系统同时具备良好的鲁棒特性和干扰抑制特性.

A two-degree-of freedom internal model control based on coprime factorization for integrating process is proposed. H2 optimization is introduced to improve the system＇s dynamic characteristics. Simulation results of a second order non-minimum phase process show that the system has good robustness and disturbance rejection performance.
