APPLICATION OF CLOSED-LOOP GAIN SHAPING ALGORITHM TO NONSQUARE SYSTEMS WITH MULTIPLE TIME DELAYS

摘要

In order to improve the robustness of industrial nonsquare systems with multiple time delays, a reformative closed-loop gain shaping algorithm (CGSA) was presented. The robust control design algorithm for nonsquare systems was given through solving the pseudo-inverse of the nominal plant without multiple time delays. Simulation results show that the robust controller can keep the set inputs without overshoot and steady state error, the regulating time is 300 s. The controller has good robustness to the model perturbation. The algorithm given in the paper has the advantages of simple design procedure and obvious physical sense.
