This paper is concerned with the design of Multi-Inputs and Multi- Outputs (MIMO) predictive PID controllers, which have similar performance to that obtainable from model-based predictive controllers. A new PID con-trol structure is defined which incorporates the prediction of future outputs and uses future set point. A method is proposed to calculate the optimal val-ues of the PID gains from generalised predictive control results. A decentral-ized version of the predictive PID controllers is presented and the stability of the closed loop system is studied. Simulation studies demonstrate the supe-rior performance of the proposed controller compared with a conventional PID controller. The results are also compared with generalised predictive control solutions.
