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

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.

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.
