The Smith delay compensator is used in multivariable non-square systems with multiple time delays where there is more number of inputs than the outputs. For the delay compensated system, centralized multivariable PID controllers are designed by the pseudo inverse technique for the steady-state gain matrix. A method is proposed to select the two tuning parameters in Davison method. To show the improvement, PI controllers for the uncompensated system are also designed by the Davison method. The performance of the multivariable delay compensated system with the centralized PI controllers is improved by 25–35% when compared to that of the multivariable control system without any delay compensator. It is also shown that the performance and robustness of the delay compensator are significantly better for the non-square systems than that of the squared down systems. Matlab Simulation and simulink tests are performed on the system and it is demonstrated in this paper.
