Iterative learning control law with variable learning gain
可变学习增益的迭代学习控制律

An iterative learning law with variable gain is proposed based on iterative learning control theory.The convergence is strictly proved mathematically and sufficient conditions are obtained.The control law is then applied to the excitation control of synchronous machines in single machine to infinite system.Simulations are also performed by MATLAB/SIMULINK in the single machine to infinite system to demonstrate the validity and universality of the method.
