Abstract

The principle of modified repetitive control is analyzed. According to the model of tracking actuator, a simplified design method of modified repetitive control was introduced. The simulation result shows the modified system has good performance. Compared with classical control system, it increases servo accuracy and steady state robustness, decreasing error signal greatly.
