RTD-A控制器在多变量系统中的研究与应用

Research and Application of RTD-A Controller for Multiple Input Multiple Output (MIMO) System

摘要: 在Ogunnaike等提出的单变量RTD-A（Robustness，Tracking，Disturbance rejection—overall Aggres-siveness）控制器的基础上，推导出了适用于多变量系统的RTD-A控制器形式，并给出了多变量控制作用求解条件的证明．仿真结果表明，与全解耦内模PID（Internal Model Controller-PID，IMC-PID）控制器相比，推导出的多变量RTD-A控制器在设定值跟踪、克服负荷扰动上都具有优异的控制性能，有很强的鲁棒性．

Abstract: Based on the univariate RTD-A(Robustness,Tracking,Disturbance rejection—overall Aggressiveness) con-troller proposed by Ogunnaike et al,a new RTD-A controller suitable for multivariable systems is presented and conditions of solution to the multivariable control action is also proved.Simulation results indicate that,compared with the decoupling IMC-PID(Internal Model Controller-PID),the derived multivariable RTD-A controller has good performances in set-point tracking,disturbance rejection and robustness.
