%X The tracking robustness of the system reflects the peak value of the output error. By defining it with the linfinity norm and linear matrix inequalities(LMIs), we propose a method for evaluating the tracking performance of a MRILQ(model-reference inverse linear quadratic) optimal current-control system. An interior permanent magnet synchronous motor is employed to simulate the optimal current-control with step or sinusoidal inputs, as well as the speed control. The results demonstrate that the system can achieve the exact tracking of current and the accurate speed control by rational parameter choices. The results also show the strong robustness against parameter variations and load disturbances.
