摘要:This paper addresses the problem of performance assessment for MIMO PID controllers.An efficient comparative analysis is established using two Iterative Linear Matrix Inequality (ILMI)approaches. To evaluate the robustness and the performances of each ILMI approach, four testsare carried out on the closed-loop system including White Gaussian noise, set point changes,parametric perturbation, and multiple time-delays influence. Different performance criterion suchas IAE, ISE, ITAE and ITSE are also presented to evaluate the closed-loop system performances.The quadruple-tank process as a benchmark of minimum/non-minimum phase systems is applied toshow the effectiveness and utility of the proposed analysis. The comparative analysis between thetwo PID controllers leads to nearly similar performance results in parametric perturbation andnoise attenuation but different results in terms of set point changes, multiple time-delays influenceand performance indices.
