In order to deal with more serious beam loading effect，an iterative learning control method was put forward. However, in previous method controller uses only proportional control. Taking into account the actual situation, its control performance still has room for improvement. For this reason, an iterative learning control based on norm optimization algorithm is applied to LLRF simulation model. The control method and result will be summarized in this paper.
