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

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.
