In order to improve the robustness of industrial non-square systems with multiple time delays, contrary to omitting the time delays as a model perturbation, a reformative closed-loop gain shaping algorithm (CGSA) was presented using Padé stable approximation of time delays. The algorithm is more precise and concise to design the robust controller. The simulation results show that the robust controller can keep the set inputs without overshoot and steady state error, the results are satisfactory. And the control effects are a little better than those in previous papers. Journal of Nature and Science, 1(2):e41, 2015.
