Many control system design methods are developed based on the dynamics of the accurate plant model. However, desired control performance cannot be achieved by the designed controller if the modeling error is not small. To overcome this problem, we have proposed a compensator to minimize the gap between an actual plant and its nominal model in SISO setting. The compensator design problem has been reduced to the standard LMI design problem and the modeling error is minimized. Consequently, the desired control performance can be achieved if we use the designed controller with our proposed compensator. The design method is extended to MIMO systems. In particular, not only error between compensated system and model, but also magnitude of the compensation input are handled in the compensator design. The effectiveness is shown by the numerical examples.
